摘要
采用离子选择电极为检测器,研究了在流动注射分析中电极响应范围与实验条件的关系,提出了水中阴离子洗涤剂的流动注射分析方法,浓度为4.0~100mg/L时,测定频率80~100次样/小时,相对标准偏差≤3.0%,回收率97~104%。
A method for FIA determination of anionic detergents in water was proposed, and the relationships between the experimental conditions of a flow injection system and linear response range and detection limit of the liquid membrane anionic detergent selective electrode were given. The relative standard deviation is≤3.0%, recovery 97—104% for the LAS concentration range 4.0—100mg/L, and sampling frequency 80—100 samples/h.
