摘　　要：利用Luminol H2O2 OP Pt(Pd)化学发光新体系以及Kalman滤波化学计量学方法建立了流动注射化学发光法同时测定铂钯的新方法。方法的检出限:铂为2.2×10-8g mL、钯为2.4×10-8g mL,铂钯相对标准偏差分别为0.9%和3%。采用阳离子交换树脂静态吸附分离,消除贱金属离子的干扰。可用于贫铂矿中铂、钯的同时测定。FI-CL system, Luminol-H_2O_2-OP-Pt(Pd), for simultaneous determination of trace Pt and Pd by Kalman Filter analysis was reported in this paper. The detection limit of the method is 2.2×10^(-8) g/mL and 2.4×10^(-8) g/mL, the relative standard deviation is 0.9% and 3% for Pt, Pd, respectivity. Cationic exchange resin acts as masking agent. A fast, convenient and sensitive method for the determination of trace Pt and Pd is described.
