Raxxye:


I want to say a hearty thank you for your very useful contributions here, Prof.
I took time to read through your every post on this thread (and that took me some two days) and I must say I'm wowed by your vast knowledge in virtually every area related to science and engineering!
If I had seen your posts two years earlier, I guess I would have been better guided in my research choice area. Nevertheless, I'm happy for the guidance you are offering here and it has really opened my eyes to see that research does pay afterall.
I am a PhD student of Environmental Geophysics here in Nigeria, working on subsurface tracer transport monitoring using 3D electrical resistivity methods.
I'll be reaching out to you for some advice relating to obtaining software for analysis and publications in reputable journals.
Once again, thank you for finding time to respond to just about every question and for the very resourceful posts you make in here!

Good evening everyone,
I am so pleased to have found this thread. I am contemplating going for my PhD programme but what I am seeing here is really making me scared, as if it will be a very challenging task and if I will be up to it. However, from observation, the thread consist of more science scholars, I may be wrong as I have not gone through the entire pages.

I am an intending PhD student, with
B.Sc Political Science(UNN)
M.Sc Public Administration (NOUN)

I am considering Public Sector Management or Human Resource Management for PhD but in Imo State University(IMSU)

Areas I need clarification are:
1. Are there possibilities to get funding for Social Sciences courses and for Nigerian Universities?

2. What are the procedures for PhD? Must I first get a supervisor, get research topics and have published works before I can apply?

3. For my chosen areas for PhD, following the trend, which area is more promising to venture into.

4. Can I be working and running a PhD programme?

Thanks everyone. God bless us...

That’s fantastic. I have worked on many agro wastes and I have enhanced their adsorptive capacity for various pollutants.

You can let me know which you are interested, which adsorption system (batch or column) you want to use, which pollutant you are considering, single or multiple pollutants, laboratory/simulated or real wastewater, how you intend to carry out the regeneration and reuse of the adsorbent, which kinetics, isotherm and thermo studies you are considering, will you be doing data optimization to enhance the parameters for industrial use? You are aware the adsorption is not a destructive tech so what happens to the spent adsorbents ?

You can reply here let people gain as well..

Prof Wip7, Sir my interest is to eliminate heavy metals in drinking water in my area, we have high cases of kidney problems, I am just suspecting the heavy metals in our area and the septic tank pollution. Which technology can i developed to be adopted at households to treat their water of heavy metals before drinking. Need Guidance.

Hello everyone..

Please what school(s) in Nigeria offer PhDs without course work? I mean thesis only PhDs?
Thanks.

There are various heavy metals contamination that leads to poisoning and kidney problems including Arsenic, Lead, Cadmium and Mercury......Take note, the kidney is the first target organ of heavy metal toxicity. The extent of renal damage by heavy metals depends on the nature, the dose, route and duration of exposure.

So before you design any treatment technology, you must identify which heavy metal contained in the water, concentrations which will be compared with permitted limits/standard and possible routes/source of contamination.

To do that test, you will need to collect the water at different points and time ...if you have Water testing kits and skilled you can analyze the water or rather take the samples to lab using AAS to detect the dosage. Collecting the water at various spots or sources will likely help you to locate the route of the heavy metal. Ensure the water collection bottles are not contaminated before being used.

After analysis, then you can design either physical(adsorption) or biological (plant or organism) or hybrid treatment method in a small scale to evaluate the efficiency of the methods against the real and treated water samples.....then the effective method can be scaled up.....

7. When you click on about the journal, you will find relevant information like the aims, type of manuscript accepted and details
8. To know if the Journal is FREE or You have to pay to publish, click the GUIDE for Authors
9. So, in the Guide for authors, go down until you get to a point that shows SUBSCRIPTION, if it gives you details about the Subscription, then means this is a free journal to publish unless you choose OPEN access. So if you want it FREE just select their regular SUBSCRIPTION (what its means is that, after you publish your paper will be on their website and only universities or individual that subscribed can download a complete paper).
10. The details below in the Guide for Authors show you how to format your work and all details needed
11. To find the coverage or database the journal belongs, kindly visit Clarivate website (https://mjl.clarivate.com/search-results). Here, you will see the true database.

Note, there are a bunch of fake journals, especially the many indian publishers' ([b]this is not a stereotype, just my observations and widely known trend) they just charge you to publish in their Journals. So, the usually list fake database or impact factors on their websites, kindly visit Clarivates for authentic coverage. [/b]

I hope this helps...........best wishes!

Greetings Prof @Wip7 and everyone in this thread. Sir I must confessed that your contributions to this thread has been highly motivational and charging. I am a prospective MSc student (Forestry and Wood Science) as I have been admitted but resuming next year. Currently I am volunteering as an intern with my undergraduate supervisor because I am really interested in research. I will like to ask questions based on this but I will like to say it is not a PhD research work but BSc for one of my supervisor's student. He is working on a topic which looks similar to this. He is working on removal of heavy metal in contaminated water using 3 different species of sawdust. He is working on batch adsorption system and he is collecting real water waste. He is using AAS to detect the heavy metals and removing the predominant one. I am interested in the work and I will like to get your advise on the experimental procedures as I wish to contribute to the work and learn from it.

Thank you in advance sir

Adsorptive Treatment of Heavy metal-contaminated water using Sawdust (biomass)

This sounds interesting. You can follow these steps and may modify them to suit your need. You will need to divide the entire work into 6 stages:

Stage 1
1. Sampling: a collection of the water samples at different sources/spots within the research zone/site.
2. Analyzing the heavy metal content of the water samples before treatment (record the concentrations and focus on the most prevalent heavy metal)
3. Storage of the water samples for further use.

Stage 2
1. Collection of adsorbent (sawdust) samples
2. Pretreatment of the sawdusts (washing with distilled water, drying and pulverized to uniform particle size) and label each (example S1, S2, S3)
3. EDTA functionalization of the S1, S2, S3 to produce heavy-metal selective adsorbent which can be named S1-EDTA, S2-EDTA and S3-EDTA.
Note: You will have 6 samples (Functionalized sawdust and raw pre-treated sawdust)
4. Pulverized all the samples (adsorbents) to a uniform size (note down the size)

Stage 3
Characterization: each adsorbent sample must be characterized. These are common characterization you can do:
a. Proximate/ultimate analysis
b. Boehm analysis
c. pH Point zero charge determination/zeta potential determination
d. Surface area (BET), pore volume and pore distribution
e. FTIR, SEM, TGA

Stage 4
Batch Adsorption process: here consider varying the following parameters for each adsorbent
a. adsorbate pH
b. adsorbent dosage
c. Treatment temperature

Stage 5
1.Kinetics (varying the treatment time): Consider fitting your data into pseudo-first order, second order, Elovich, intra-particle diffusion etc.
2. Isotherm (Varying adsorbate concentration): Consider fitting your data into Langmuir, Freundlich, Redlich-Peterson, Temkin etc
3. Thermodynamic study (obtained from the temperature change)

Stage 6
Desorption, regeneration and recycling of the spent adsorbents
Economic and cost-benefit analysis regarding the treatment tech.
Comparative performance of your adsorbents and reported adsorbents for heavy metal removal

NOTE:
Functionalizing with EDTA will be useful to compare the performance of the adsorbent. by comparing the concentration of the heavy metals before treatment to after the treatment. Why EDTA? See below:

EDTA is a chemical that binds and chelates metals such as chromium, iron, lead, mercury, copper, aluminium, nickel, zinc, calcium, cobalt, manganese, and magnesium from water......and when they are bound, they can't have any effects and they are removed from the water.

If that's my master student above steps are what I will give.....please visit Science directly to find suitable articles to support you. Also, you can email me, I will send you some of my recent top-quality journals of adsorption treatment of heavy metals.

Best wishes
