锰取代杂多酸/石墨烯复合材料的制备及吸附性能

Preparation and adsorption performance of manganese substituted heteropoly acid/graphene composites

制备了α-SiMo11Mn/GO复合材料,使用IR、UV和XRD进行了表征。研究了α-SiMo11Mn/GO的吸附性能,考察了pH、吸附剂用量和染料初始质量浓度对亚甲基蓝吸附效果的影响,确定了优化条件:pH为9、吸附剂用量50 mg/L、亚甲基蓝初始质量浓度10 mg/L,在该优化条件下最大吸附率为88.82%,最大吸附量为57.76 mg/g。

The compositesα-SiMo11Mn/GO was synthesized and characterized by IR,UV and XRD.The adsorption performance ofα-SiMo11Mn/GO composites was studied.The effects of pH,catalyst dosage and initial mass concentration of dye on the adsorption rates of methylene blue were investigated.The optimal con⁃ditions were determined:pH 9,the dosage ofα-SiMo11Mn/GO 50 mg/L,the initial mass concentration of methylene blue 10 mg/L.Under the optimal conditions,the adsorption rate was up to 88.82%,and the adsorp⁃tion capacity could reach 57.76 mg/g.
