Abstract
Abstract Chitosan was grafted with polyorthoethylaniline through oxidative polymerization using ammonium persulfate as oxidant, resulting in the formation of a biocomposite of chitosan-grafted-polyorthoethylaniline (CH- g -POEA). The synthesized biocomposite (CH- g -POEA) was characterized by FTIR, SEM, and TGA. Adsorption of methyl orange (MO) dye by CH- g -POEA was studied, wherein the Langmuir isotherm model with a R 2 of 0.9979 and adsorption capacity of 45.7 mg/g was evaluated.
