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. Graphical abstract

一种新型壳聚糖接枝聚邻乙基苯胺生物复合材料的合成与表征及用于去除水中染料的应用

摘要 以过硫酸铵为氧化剂，通过氧化聚合将壳聚糖与聚邻乙基苯胺接枝，形成壳聚糖接枝聚邻乙基苯胺（CH-g-POEA）的生物复合材料。合成的生物复合材料 (CH-g-POEA) 通过 FTIR、SEM 和 TGA 进行表征。研究了CH-g-POEA对甲基橙(MO)染料的吸附，其中评估了R 2 为0.9979和吸附容量为45.7 mg/g的Langmuir等温线模型。图形概要
