摘要/Abstract

摘要： 4A沸石可部分或全部代替三聚磷酸钠,以减少合成洗涤剂对水质富营养化的影响,在硬水中使用也不致降低洗涤效力.本文研究了4A沸石在不同pH水溶液中和无机盐存在下对氯化十四烷基吡啶(TPC)的吸附作用,初步探讨了吸附机制.

Abstract: The adsorption isotherms of tetradecylpyridium chloride (TPC) from aqueous solutions (before adsorption,pH 4～11) on zeolite 4Ahave been determined at 25℃.All the isotherms are of Langmuir type and similar ones.The result can be explained in that zeolite 4Ahas a quite large buffer ability,and pHvalues of the solutions before adsorption are close (pH 9～10).In the range of pH 8～10 the electroretic mobilition of zeolite 4A is a constant value.After adding NaCl and CaCl₂,the adsorption of TPC in lower concentration decreases markedly and the kind of the isotherms can be transform into Stype.
