通过对高岭土进行表面改性制备了高岭土 MBT复合体 ,并考察了其对水溶液中某些重金属离子的吸附性能。结果表明 :高岭土 MBT复合体对水中Pb2 +、Hg2 +、Zn2 +的吸附能力明显优于纯高岭土和仅经过表面处理的高岭土 ,其对Pb2 +、Hg2 +、Zn2 +的最大吸附量分别为 16 91μmol·g- 1、2 0 5 2 μmol·g- 1和 10 80 μmol·g- 1。
The kaolinite MBT composite was prepared by surface modification of kaolin, and its adsorption performance on some heavy metal ions in aqueous solution was investigated. The results show that the adsorption capacity of Pb2 +, Hg2 + and Zn2 + in kaolin MBT composite is better than that of pure kaolin and kaolin treated only with surface treatment. The maximum adsorption capacity of Pb2 +, Hg2 + and Zn2 + 91 μmol · g -1, 1,2 0 5 2 μmol · g -1 and 10 80 μmol · g -1.
