摘要
文章依据硫酸镁转化法制取硫酸钾相图,配制25℃下Mg2+,K+//Cl-,SO2-4-H2O体系硫酸钾饱和溶液,用结晶槽法研究了该体系溶液在不同过饱和度下,硫酸钾晶体的线生长速率。硫酸钾结晶动力学实验结果表明,所研究溶液体系硫酸钾晶体生长由表面反应过程控制。
The saturated solution of potassium sulphate is got basing on the phase diagram of Mg^(2+),K^+//Cl^-,SO^(2-)_4-H_2O at 25℃,the line growth rate of potassium sulphate crystal was studied in the aqueous system in microscopic cell.The result showed that the process of crystallization of potassium sulphate belongs to the control of surface reaction in given system.
