Adsorption of Dyes and Metals
Project Summary: This page summarizes research efforts on the adsorption of organic dyes and toxic metals from aqueous solutions using engineered and low-cost sorbents.
Key Contributions:
- Lead author of a study applying ML and experimental design for methylene blue removal using bone meal
- Developed framework based on point of zero charge (pHpzc) to evaluate biochars for cationic dye adsorption
- Co-authored a work on synthesis and characterization of yttrium silicate for Pb(II) and Cd(II) removal
