摘　　要： 利用鲁米诺—铁氰化钾发光体系,结合流动注射技术,建立了一种对饮用水中Cd(Ⅱ)浓度实时监测的新方法。在最佳实验条件下,该方法的线性范围为5.0×10-4～5.0×10-2mg/mL,检出限为2.6×10-5mg/mL,RSD为1.9%(n=11)。结果表明,该方法具有检测范围宽,简单快速,成本低廉等优点,能实现对江河水和饮用水Cd(Ⅱ)突发性污染的在线监测,为将来构建饮用水预警机制提供技术支持。 A new novel for real-time monitoring of the concentration of Cd（II） in drinking water was established by utilizing Luminol-potassium ferricyanide chemiluminescence system combined with flow injection technique.Under the optimal experimental condition,the linear range for Cd （Ⅱ）determination was 5.0 x 10^-4-5.0 x 10 z mg/mLThe detection limit was 2.6 x 10-Smg/mL.And the relative standard deviation for the determination was 1.9% （ n = 11 ）.As the result indicated, this method had the advantages of wider detection range, simpler and faster operation, as well as lower cost.This method could realize the on-line monitoring of sudden Cd （Ⅱ） pollution in rivers and drinking water and provide technical support for the construction of early warning mechanism.
