Determination of sulfide by low pressure ion chromatography

摘要

An amperometric follow-injection system is proposed for the rapid determination of sulfide in leather-making process by using low pressure ion chromatography (LPIC). A special anpere detection cell was developed. Compared with the routine chemical analysis. it has many advantages such as high accuracy, high sensibility and rapid. It can save over 95 percent of themical reagents wiht lower than 1.7 percent of variation coefficient and 95 approx percent of its recovery ratio. The results obtained by amperometric flow injection analysis (FIA) is satisfactory.
