摘要: 为探究三赞胶复合微球对亚甲基蓝染料的吸附性能,将膨润土和高岭土分别与三赞胶共混制备成复合微球,系统考察了亚甲基蓝溶液初始质量浓度、吸附时间和溶液pH值对复合微球吸附效果的影响,并确定了最佳吸附条件。结果表明:三赞胶/高岭土复合微球的吸附性能低于三赞胶/膨润土复合微球;在温度为25 ℃、亚甲基蓝初始质量浓度为600 mg/L、吸附时间为24 h、pH值为11的条件下,三赞胶/膨润土复合微球对亚甲基蓝的吸附量为149.1 mg/g,去除率为96.3%,吸附过程符合Langmuir等温吸附模型;试验证明三赞胶复合微球对亚甲基蓝具有优异的吸附性能。本研究结果为废水染料处理提供了新思路,同时为相关领域的进一步研究和应用奠定了基础。

Abstract: In order to investigate the adsorption performance of the composite microspheres of sanxan gum on methylene blue dye, bentonite and kaolin were blended with sanxan gum to prepare composite microspheres, and the effects of different initial concentration of methylene blue solution, adsorption time and pH value of solution on the adsorption effect of the composite microspheres were investigated through experiments to determine the optimal adsorption conditions. The results showed that the adsorption performance of the composite microspheres of sanxan gum/kaolin decreased compared with that of the composite microspheres of sanxan gum/bentonite, and the adsorption amount of the composite microspheres of sanxan gum/bentonite reached 149.1 mg/g with a removal rate of 96.3% under the optimal experimental conditions of initial concentration of methylene blue at 25 ℃, adsorption time at 24 h, and pH at 11. The adsorption process of methylene blue by sanxan gum composite microspheres was in accordance with Langmuir isothermal adsorption model. This study provides a new idea for the treatment of wastewater dyes and confirms the good adsorption performance of sanxan gum composite microspheres on methylene blue.
