Abstract

Synthesis of chitosan-GO composites using the sol-gel method and its application to methylene blue adsorption has been carried out. This study aims to determine the ability of chitosan-GO composites to adsorb methylene blue. Chitosan-GO composites were made with mass ratios (1:1), (1:3), and (1:5) and characterized by XRD. Material with a ratio (1:1) was chosen to be characterized using BET, SEM-EDS, and used as methylene blue adsorption. Methylene blue adsorption process with several variables including contact time, concentration, and temperature of methylene blue dye. The results of the XRD characterization of the chitosan-GO composite (1:1), (1:3), and (1:5) showed a diffraction peak at an angle of 2θ, namely 25.1°; 26.29° and 19.54°. The surface area of the chitosan-GO composite (1:1) with BET was 145.3505 m2/g. Characterization using SEM showed that the chitosan-GO (1:1) composite had a porous structure and was not homogeneous. Optimum conditions for the adsorption of the chitosan-GO composite on methylene blue were obtained at 50 minutes contact time, concentration of 60 ppm, and at 50°C. The adsorption process of the chitosan-GO composite on methylene blue followed the Freundlich adsorption isotherm with an adsorption capacity of 2.47 mg/g.

利用溶胶-凝胶法合成壳聚糖-氧化石墨烯（GO）复合材料及其在亚甲基蓝染料吸附中的应用

利用溶胶-凝胶法合成了壳聚糖-GO 复合材料，并将其应用于亚甲基蓝吸附。本研究旨在确定壳聚糖-GO 复合材料吸附亚甲基蓝的能力。壳聚糖-GO 复合材料的质量比分别为 (1:1)、(1:3) 和 (1:5)，并通过 XRD 进行了表征。选择比例为（1:1）的材料使用 BET、SEM-EDS 进行表征，并用作亚甲基蓝吸附材料。亚甲基蓝吸附过程有几个变量，包括亚甲基蓝染料的接触时间、浓度和温度。壳聚糖-GO 复合材料（1:1）、（1:3）和（1:5）的 XRD 表征结果显示，在 2θ 角处出现了衍射峰，即 25.1°、26.29° 和 19.54°。壳聚糖-GO 复合材料（1:1）的 BET 表面积为 145.3505 m2/g。利用扫描电镜进行的表征显示，壳聚糖-GO（1:1）复合材料具有多孔结构，且不均匀。壳聚糖-GO 复合材料对亚甲基蓝的最佳吸附条件是接触时间为 50 分钟、浓度为 60 ppm、温度为 50°C。壳聚糖-GO 复合材料在亚甲基蓝上的吸附过程遵循 Freundlich 吸附等温线，吸附容量为 2.47 毫克/克。
