摘　　要：流动注射ｐＨ梯度技术－卡尔曼滤波分光光度法同时测定铜钴镍多元混合物毛东森，张国莹，陈同岳（上海工业大学化学化工系，上海，２０００７２）关键词：流动注射分析，梯度技术，卡尔曼滤波，分光光度法，同时测定探索不经任何分离而同时测定多个相互干扰组分混合物的分...This paper covers the Simultaneous determinations of coppet,cobalt and nickel in their binary and ternary mixtures by pH gradient technique in flow injection analysis with RAR as the chro mogenic reagent. Kalman filter is used to analyze the data provided by this method. the recoveries of the method are 95-105% and 94-108%for binary and temacy mixtures respectively.The rel ative standard deviations are lass than 2.5%.
