Current Research Interest

Chemical modification of biosorbent is a common practice in wastewater treatment when using adsorption technology to increase the ion exchange capacity and physical stability. Citric acid and other organic acids are currently being investigated for their ability in modifying biosorbents for the removal of some cations and anions; as well as dyes from aqueous medium.

This method has been applied for the removal of phosphate and sulphate ions using citric acid and tartaric acid modified Albizia lebbeck. This chemical modification is being extended to other biosorbents to enhance their sorption capacity for other anions, cations, dyes, phenols, etc.
