| 摘 要： | 流动注射胶束增容法测定水环境中的铜，方法简便快速，便于水环境中铜离子的测定。在硼砂盐酸缓冲溶液中，铜与铬天青S以及溴化十六烷基三甲基铵（CTMAB）反应生成黄绿色的络合物，在605nm波长下可以检测。在最佳检测条件下，运用该方法测定铜离子可以得到线性良好且范围广的标准曲线，检测范围为5～40μg／L、40～200μg／L；检测限为0．76μg／L；相对标准偏差为1．59％（n=11）。试验得到的回收率为90．2％～104％。

| Abstract: | Copper in environmental water can be determined by flow injection analysis micelle-solubilized spectrophotometry.This method can detect copper quickly and convenitly.In the buffering solution of Na_(2)B_(4)O_(7)-HCl,copper reacted with CAS(chrome axurol S) indicating color with in the presence of CTMAB(hexadecyl-trimethylammonium bromid),a Kelly substance was made,then determined in 605 nm.Under the optimum condition,standard curve with good linearity and broad liner range can be obtained among the ranges of 5-40 g/L and 40-200 g/L;the detection limit was 0.76 g/L and the relative standard deviation(slope) was 1.59%(n=11);and the range of recovery was 90.2%-104%. |
