摘要
合成了复合材料β_(3)-SiW_(11)Ni/GO。用红外光谱、XRD和SEM对样品进行表征;并对吸附剂用量、染料初始质量浓度、溶液pH等条件进行探究,确定反应优化条件。实验表明:β_(3)-SiW_(11)Ni/GO的优化吸附条件为溶液pH6、吸附剂用量10mg、甲基橙初始质量浓度35mg/L,此时的去除率为91.58%,最大吸附量可达138.65mg/g。
The composite material β_(3)-SiW_(11)Ni/GO was synthesized.The samples were characterized by infrared spectroscopy,XRD and SEM.The input amount of adsorbent,the initial mass concentration of dye,the pH value of the solution and other conditions were explored,and the optimal reaction conditions were determined.The results showed that the optimal adsorption conditions for β_(3)-SiW_(11)Ni/GO were:the pH of the solution was 6,the adsorbent input was 10 mg,and the initial mass concentration was 35 mg/L.At this time,the removal rate was 91.58%,and the maximum adsorption capacity could reach 138.65 mg/g.
