摘要
以Co取代的硅钨酸为活性组分,采用界面聚合法合成β_(2)-SiW_(11)Co/GO/PANI复合材料,并应用紫外光谱、红外光谱、X射线衍射等进行表征。以β_(2)-SiW_(11)Co/GO/PANI对染料甲基橙进行吸附实验。结果表明,在甲基橙溶液质量浓度为30 mg/L、pH为6,复合材料用量为9 mg时,吸附效果较好,脱色率为91.09%,吸附量达到153.89 mg/g;β_(2)-SiW_(11)Co/GO/PANI对甲基橙的吸附过程符合准二级吸附动力学方程。
Using Co-substituted silicotungstic acid as the active component,the β_(2)-SiW_(11)Co/GO/PANI composite material was synthesized by interfacial polymerization,and characterized by ultraviolet spectrosco⁃py,infrared spectroscopy and X-ray diffraction.The adsorption experiment of β_(2)-SiW_(11)Co/GO/PANI on the dye methyl orange was studied.The results showed that when the mass concentration of methyl orange solution was 30 mg/L,pH 6,and the amount of composite material was 9 mg,the adsorption effect was well,the de⁃colorization rate was 91.09%,and the adsorption capacity reached 153.89 mg/g.Moreover,the adsorption ex⁃periment of β_(2)-SiW_(11)Co/GO/PANI on methyl orange accorded with the quasi-second-order adsorption kinetic equation.
