摘要
本文研究了铬(Ⅲ)在聚合硫酸铁(PFS)胶体上的吸附行为和机理,认为PFS 与铬(Ⅲ)的作用是一个吸附一共沉淀的共同作用过程,得出了相应的数学模式.重点讨论了铬(Ⅲ)浓度,PFS 用量、干扰离子和溶液 pH 值对吸附共沉淀的影响,及吸附的最隹工艺条件.此外还研究了铬(Ⅲ)的再生.用实验所得最隹工艺条件处理工厂含铬废水,证明效果良好.
The behaviour and mechanism of adsorption of Cr(Ⅲ)to the Colloid Solut- ion of Polymerizing ferrie Sulphate(PFS)have been Studied,It is believed that the action of PFS to Cr(Ⅲ)is a Coaction of adcorption and Coprecipitati- on,and the elementary model of adsorption is achieved.The discussion centred on the effect of Cr(Ⅲ)Concentration.PFS Concentration,disturbing ions. and PH in Solution of adsorption,and Optimum technical Conditions.In addit- ion,Cr(Ⅲ)reproduction has also been researched,Accordiong to the Optimum technical Conditions,the treatnieat of Cr(Ⅲ)Wastewater from the factory, is satis factory。
