Abstract

The method of spectrophotometric determination of palladium(II) with a new, first synthesized reagent – 5-hydroxyimino-4-imino-1,3-thiazolidin-2-one, in the medium of acetate buffer solution (pH=5.0) at constant ionic strength of the solution have been elaborated. The range of the determined concentrations of Pd(II) is 0.6-6.4 μg/ml. The selective of palladium(II) determination with 5-hydroxyimino-4-imino-1,3-thiazolidin-2-one relative to different concomitant ions has been investigated. The elaborated method has been approved during the analysis of model solutions and the industrial sample.

Keywords: palladium(II), spectrophotometry, 5-hydroxyimino-4-imino-1,3-thiazolidin-2-one, azolidons
