岩石对Zn2+、Pb2+的竞争吸附特征
Characteristics of Competitive Adsorption of Pb2＋and Zn2 in Rock
摘要
Abstract
Under static state condition, the characteristics of adsorption of Pb2＋and Zn2 in Rock have been studied using the ultraviolet-visible spectrophotometers method and the atom adsorption spectrophotometers method. The results show that the process，in which the sandstone adsorbs Zn2＋ from solution-containing Zn2＋, the sandstone adsorb Zn2＋ and Pb2＋ from Pb2＋+Zn2＋ solution and breccia adsorbs Zn2＋ from Pb2＋+Zn2＋ solution , is fractal-like. The rate of adsorption of Pb2＋ is more than that of Zn2＋ in breccia. The adsorption ability of Zn2＋ in rock is decreased because there is Pb2＋ in solution. The adsorption capacity of Pb2＋ is close to that of sandstone and breccia,and the adsorption ability of Zn2＋ in breccia is better than that in sandstone.关键词
