摘要
研究了流动注射分光光度法快速测定制革循环水中硫化物含量的方法,该方法(显色剂为对二甲氨基苯胺)测定波长为665nm,工作范围:ρ硫离子=2.0~25.0mg/L,进样频率为每小时100样,相对标准偏差0.96%,回收率96%~101%。
The paper studied a high speed analytical method which could be applied to detect the content of sulfide in circulating water in leather industry.Reagent is a N,N dimethylaniline.Working wave length is at 665 nm.The range of Calibration curve is in 2.0~25 mg/L.The sample can be analyzed 100 per hour.RSD is 0.96%.The recovery percent is 96%~101%.
