Abstract

In the presence of CTMAB,a colour reaction of Pd(Ⅱ) with crystal violet has been studied.In an acetate buffer medium(pH=4.6),the complex has an absorption maximum at 620 nm.The molar absorptivity is e 620 =1.3×10 5 L/mol·cm.Beer's law is obeyed in the range of 0～5.0 μg/mL for Pd(Ⅱ).The method has been applied to determine the content of Pd in the catalyst with satisfactory results.
