| 摘 要： | 通过对广西田东钙基膨润土的酸化脱色实验研究，表明活性土的脱色能力是其表面积和酸化作用中浸取出的铝离子量的函数；在钙蒙脱石晶体结构处于彻底破坏前的临界点，膨润土具有最大的脱色能力和比表面积。

| Abstract: | The decoloring ability of Ca-bentonite from Tiandong, Guangxi, which was obtained byacidation of bentonite, has been determined as a function of its surface area and amount of alumi-num cations removed from the octahedra of montmorillonite. During the acid curing, the greatestdecoloring ability and surface area of bentonite were achieved at the crystal structure collapse'scritical point of Ca-montmorillonite. |
