沸石离子交换法制碳酸钾

THE PREPARATION OF POTASSIUM CARBONATE BY ZEOLITE ION-EXCHANGE METHOD.

介绍了沸石离子交换法制Ｋ２ＣＯ３技术，Ｋ＋、ＮＨ＋４分别交换并回收循环洗液，提高了Ｋ＋、ＮＨ＋４的利用率。溶液经喷雾干燥得到Ｋ２ＣＯ３。简化了工艺过程。

The technique for the preparation of K 2CO 3 by zeolite ion-exchange method is introduced.The exchange of K + and NH + 4,and the recovery of circulation washings can increase the utilization rate of K + and NH + 4,and the recovery of circulating washings can increase the utilization rate of K + and NH + 4,The solution is dried by spraying dryer to obtain K 2CO 3 product,thus the process can be shortened.
