  Abstract

Methyl orange plays a vital role in various branches of the dyeing and textile industries and must be treated before being discharged into the environment. In this study, methacryloxyethyltrimethyl ammonium chloride (DMC) functionalized cotton linter (DMCCL) was prepared using a radiation technique. The prepared DMCCL was then characterized by IR, SEM, TG, and XPS analyses. The results showed that DMC was successfully grafted onto the surface of the cotton linter. The adsorption performance toward methyl orange (MO) was investigated using batch and fix-bed column experiments. Adsorption kinetic and isotherm studies were well described by pseudo-second-order kinetic and Langmuir isotherm model, respectively. The maximum adsorption capacity for MO was 645.16 mg/g. The fixed-bed column experiment showed that Thomas and Yoon-Nelson models described the experimental data well. The column study showed the adsorption capacity reached 564.46 mg/g with a MO concentration of 25 mg/l and flow rate 1.5 ml/min. The saturated DMCCL column could be regenerated efficiently by eluting with 1 M HCl. Therefore, the DMCCL exhibited excellent adsorption performance, which is suitable for MO removal from aqueous solution.
