摘要
以氯化钾和碳酸氢铵为原料，离子交换法制备碳酸钾，采用三柱串联吸附，双柱串联洗脱工艺，能提高树脂利用率和原料、洗脱剂的利用率。
Potassium carbonate has been preparated by ion exchange process with raw material of potassium chloride and bicarbonate of ammonium.The technique of absorption by series three ion exchange columns and washing by series two ion exchange columns has been studied.With this method ,the utilization ratio of resin,raw material and washing agent can be improved.
