纳米催化还原Ni(Ⅱ)体系光度法测定痕量钯
Nanocatalytic Spectrophotometric Determination of Palladium( Ⅱ ) Using NiCl2-NaH2PO2 System
摘要
Abstract
In the medium of NaOH at 85 ℃,the reduction of NiCl2 by NaH2PO2 to NiP particle is slow,its absorbance is weak,and the blank solution is colorless and transparent. Upon addition of palladium( Ⅱ ) catalyst,the reaction accelerated,and resulted in the absorbance enhancing at 395 nm. The color changed to dark. Based on those grounds,a catalytic spectrophotometric method was established for the determination of trace Pd( Ⅱ ). Its linear range is 0. 09~1. 80 μg/L Pd( Ⅱ ) ,with a detection limit of 0. 03 μg/L Pd. This method has the advantage of simplicity,good selectivity,and high sensitivity.关键词
