摘要

  • 摘要: 以2-(5-溴-2-吡啶偶氮)-5-二乙氨基酚为螯合剂,三氯甲烷为萃取剂,采用卡尔曼滤波和分光光度法同时分析长江和嘉陵江现场采集的地表水样中Cu2+,Cd2+,Zn2+和Pb2+的浓度.4种金属离子的实验室回收率在91.0%-113.1%之间;比较长江、嘉陵江国控点例行监测数据,本方法具有较好的可比性和可靠性,能直接应用于江河水样多种金属污染物的同时定量分析.
    Abstract: Using 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol as chelating reagent and chloroform as extracting reagent,four metal ions namely Cu2+,Cd2+,Zn2+and Pb2+in water samples from directly Yangtse river and Jialing river have been simultaneously determined with Kalman filter and spectrophotometric analysis.The determinating results showed that recovery of the method is between 91.0%-113.1% to samples of laboratory.The analysis results by Kalman filtering compared with the corresponding pollution data from the governmental water quality monitoring sites has also shown a well consistency and reliability.The method could be directly used for monitoring simultaneously real samples containning multi heavy metal ions in various surface water of rivers quantificationally.
