Adsorption Of Selected Dyes By Chemically Modified Uncaria Gambir Extract

Adsorption Of Selected Dyes By Chemically Modified Uncaria Gambir Extract

Uncaria gambir extract was chemically modified to develop a novel adsorbent for the adsorption of Methylene Blue (MB), Sunset Yellow FCF (SY), and Direct Red 23 (DR 23) from aqueous solution. It was revealed that the ethyl acetate extraction of gambir showed highest total phenolic and total flavonoi...
