- 中文摘要: The color reaction of palladium(II) with the new reagent OPT was studied. In the presence of cetyltrimethyl ammonium bromide (CTMAB), in pH 5.0-5.6 Hac-NaAc buffer solution, a yellow-brown soluble complex with the ratio of 1:4 was formed. The maximum absorption was at 299.0 nm, the apparent molar absorptivity ε299.0 nm = 1.38 × 105l mol-1 cm-1. Beer’s law was obeyed in the range of 2-12 μg Pd(II)/25 mL. The method’s sensitivity and selectivity were very good. It could be used to determine palladium(II) in a catalyst with satisfactory results.
