【Abstract】 In this paper, Pd(II) in ammonium hydroxide can accelerate the decolorizing indicating reaction which results from the oxidation of Diphenylcarbazone by air, and the kinetic conditions of the reaction are studied. A new high selective method for determining trace Pd(II) has been established. The sensitivity of the method is 2.5×10-22g/ml for Pd(II).更多还原
