合成氨脱碳液DEA测定方法的改进

Improvement on Method of Determination of DEA Solution for CO_2 Removal in Ammonia Production

采用硫酸铜代替碱式碳酸铜用于铜复盐比色法测定DEA ,简化了操作 ,而且线性关系良好 ,回收率在 95 .6 %～ 1 0 2 .8%。

Basic cupric carbonate is replaced by cupric sulfate in the determination of DEA by colorimetry with copper double salt, then, the operation is simplified, the linear relationship is good, and the recovery is 95.6%～102.8%.
