【摘要】 采用普通极谱仪与计算机联机技术,用卡尔曼滤波处理以KSCN为支持电解质的Cd²⁺和Ni²⁺混合溶液的示波极谱重叠波。实验表明,极谱可逆波具有较好的加和性,可采用计算极谱方法对多组分（尤其是难以分开的重叠波）进行同时测定。更多还原

【Abstract】 The overlapping polarographic waves of Cd and Ni in 1.0 mol/L KSCN electrolyte can be resolved by using kalman filtering and a method for determing both elements simultaneously is developed. The method is simple and accurate. The average recoveries for Cd( Ⅱ)and Ni(Ⅱ )were 94. 50% and 99. 97% respectively.更多还原
