Abstract
A flow injection method was developed for the determination of palladium, b ased on the reaction of palladium with DBOK-chlorophosphonazo with a detect ion limit of 0.07 mu g/mL and a linear calibration range from 0.1 to 3.2 mu g/mL of palladium. The reaction product has a maximum absorption at 630 nm . The method was applied to determine Pd2+ in catalysts and in anode mud sa mples. The relative error is less than 3% and the recovery of palladium is in the range 95% to 105%.
