摘　　要：本文研究了2—二异丙氨基—3—甲基—5—-(4—二甲氨基偶氮苯)—1,3,4—噻二唑与钯(Ⅱ)的显色反应,确定了最佳測定条件。据此拟定了钯的分析方法。实验表明,该法精密度、灵敏度、选择性良好。用于合成样和电解铜阳极泥中钯的分析,结果满意。从而为钯的测定提供了一种新的方法。The complex can be extracted with benzene-butanone (4∶1), and the absorbance of the organic phase is measured at 675nm. The ratio of Pd to TDAA-I to butanone in the complex has been found to be 1∶3∶1. The apparent molar absorptivity is 9.19×10~4 L·mol^(-1)cm^(-1) for the complex and Beer's law is obeyed in the range of 0.00 to 1.52 μg/ml. This method has been applied to the determination of Pd in anode mud with satisfactory results.
