The main project objectives are to develop standardized methods for producing a single material (engineered porous material coated with metal) and optmize its fabrication method and performance for the removal of ammonia from water.
Methodology: porous materials will be cleaned and dried. Materials will be characterized by Scanning Electron Microscope (SEM) and pore size analysis and surface area determination via Gas Sorption Analyser, FTIR, Raman, and DTG. These particles will be coated with metal for targeting ammonia removal from water. Removal efficiency will be assessed by batch and column experiments.
Tasks and Responsibilities
The student will have to fulfill the following required responsibilities
a) Search and study literature relevant to project’s objective.
b) Clean the naturally obtained particle to remove all dust from its surface.
c) Functionalize the cleaned particle with metal- This is a two-step process which includes impregnating the cleaned particle with metal precursor and calcination of the impregnated particle at high temperature.
d) Report the change in weight of zeolite before and after functionalization
e) Characterize the prepared particles for its surface area using BET Isotherm, surface properties using Scanning electron microscope, FTIR, Raman and DTG and report the results.
f) Evaluate the adsorption efficiency of the prepared particle for ammonia by conducting experiments for adsorption kinetics and adsorption isotherms in UV/Vis spectrophotometer and report the results.
