氟化沉淀法净化硫酸锌溶液中钙镁的热力学分析

Thermodynamics Analysis of Removal of Ca^(2+),Mg^(2+) From Zinc Sulphate Aqueous Solution With Fluoride Precipitation

对氟化沉淀法净化酸锌溶液中的镁离子进行了热力学分析 .用ZnF2 作为沉淀剂 ,在较低温度和较高 pH下可有效净化溶液中的钙镁 。

This paper analyzed thermodynamics of Ca 2+ ,Mg 2+ from zinc sulphate aqueus solution with Fluoride precipitation.Using ZnF 2 as precipitant can remove calcium and magnesium from the solution effectively.Moreover,it can control accumulation of fluorine in the solution.
