摘要
本文将JP—lA极谱仪与计算机联机,进行J卡尔曼滤波极谱法同时测定镉(Ⅱ)、镍(Ⅱ)、锌(Ⅱ)、钻(Ⅱ)、铁(Ⅲ)、锰(Ⅱ)的可行性研究。实验表明,在0.10mol/L氯化钾、0.30％亚硫酸钠、0.50％水杨酸钠及在pH=8.0的氨性缓冲溶液中。上述离子的重叠峰解析良好,且不存在干扰问题。
The overlapping waves of polarography were resolved by using Kalman filter, and some elements (Cd,Ni,Zn, Co,Fe, Mn) in 0. 1 mol/L potassium chloride, 0.3% sodium sulfite, 0.5% sodium salicylate and ammonium buffer solution were simultaneously determined. The method is simple, fast and accurate. This is a good method suitable for determining microelements in copper alloy.
