【摘要】 对Ｍｇ－Ｃａ－Ｂａ三元组分体系，金属离子摩尔比介于１：１～１：２０时，回收率为９５％～１１６％；对Ｚｎ－Ｃｕ－Ｎｉ－Ｃｄ－Ｃｏ－Ｆｅ六元组分体系，金属离子摩尔比介于１：１～１：４５时，回收率为７９％～１３５％。对黄浦江水样进行分析，获得了成功。更多还原

【Abstract】 When modified Kalmanfiltering is applied to analyze Mg-Ca-Ba three com-ponents system,recoveries of results 95%～116% are gained where mole ratio of metallic ions is between 1:1～1:20. When it is applied to analyze Zn-Cu-Ni-Cd-Co-Fe six components system,recoveries of results 79%～135% are gained where mole ratio of metallic ions is between 1:1～1:45.It is succesful to analyze the actual samples of Huangpu River by using the method.更多还原
