摘要
介绍硫离子在线检测仪的测定原理和基本系统结构,仪器采用流动注射法(FIA),具有测定周期短、试剂用量少的优点,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=2.0～25.0mg·L-1。回收率为96.1%～101.8%。
The measurement principles and structure of an on-line sulfide detection instrument based on FLA are deseril,ed ,The instrument has the advantages of shorter measurement cycle and small reagent consumption. It was detected at 665 nm （Reagent is a N.N-dimethylaniline）, The linear range of calibration graphs was 2,0-25.0 mg·L^-1, and the recovet＇y rate was 96.1%-101.8%.
