摘要:

为了利用脱硫废液中的副盐,采用沉淀-溶析结晶法处理真空碳酸钾脱硫废液。通过实验确定了最佳工艺条件,该工艺能大大降低废液中的副盐浓度,同时得到K2SO4和CuSCN产品。

Abstract:

By means of precipitation-crystallization,the secondary salt in desulfurized potassium carbonate waste solution can be utilized to retrieve CuSCN and K2SO4.The optimum technological conditions are obtained through experiments.In addition,the concentration of secondary salt in waste liquid becomes much lower.
