解决对氨基二甲基苯胺光度法测定硫化物中的几个问题

DISCUSSION ON THE EXAMINATION OF SULFIDE BY P-AMINO DIMETHYLAN- ILINEDIHYDROCHLORIDE SPECTROP- HOTOMETRY

介绍对氨基二甲基苯胺光度法测定硫化物方法中如何降低空白值,提高硫化钠溶液的稳定度以及提高酸化吹气回收率的原理和方法.

This paper discussed by using P-Amino dimethylaniline dihydrochloride spetrophotomet-ry to examine sulfide, how to reduce blank value, improve the stability of sodium sulfide solution and the recovery ratio of acidification blowing.
