摘要

目的　研究低氯离子钾肥硫酸钾的制备方法

以便于技术的应用和推广 .方法　以 KCl和H2 SO4为原料

利用溶剂萃取法制取 K2 SO4.结果　通过正交实验

得出各反应条件的极差分析 .结论　得到了各因素对两步反应的影响次序

确定了最优实验条件与萃取条件

在最佳工艺条件下制取的 K2 SO4达到了国家一级品的要求

Abstract

Aim\ To study producing method of potash fertilizer (potassium sulfate) withlow chlorine ion

to apply and popularize the technology. Methods\ Use potash muriate and sulfuric acid as raw materials to produce potassium sulfate by solvent extraction. Results\ Through orthogonal experiment the difference analysis under different conditions is obtainad. Conclusion\ The effect sequence of each factor in two step reaction is obtained. The optimal condition of experiment and extraction is determined The potassium sulfates made under optimal technical condition achieved the first class products specified by national standard.
