摘要：

A flow-injection spectrophotometric method for the determination of palladium involves the measurement of the absorbance of the palladium complex with DCS-arsenazo at 635 nm. The calibration graph is linear over the range 0-8.0-mu-g ml-1. The detection limit is 0.05-mu-g ml-1. The sample throughput is 90 h-1 with 100-mu-l sample injections. The proposed method has been applied to the determination of palladium in metallurgical samples without preliminary separation.
