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 ϵ 299.0 nm = 1.38×10 5 l 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.
