Determination of trace amounts of palladium by solution scanometric method

Publication date: Available online 16 January 2017 Source:Journal of Taibah University for Science Author(s): Ardeshir Shokrollahi, Kowsar Ramdar In this research solution scanometry is presented as a highly sensitive, simple and rapid method for colorimetric determination of palladium ion in water samples and walnut leaf. The method is based on the formation of rose-brown complex between Pd2+ ion and excess of iodide in acidic medium, in the Plexiglas cells, scanning of it by conventional flatbed-scanner and analyzing the color of each cell by software written in visual basic (VB 6) media to red, green and blue values. The relative standard deviation and linear range of the method were found to be 1.0% and 0.1-72.0μgmL−1, respectively. The proposed method was successfully applied for the determination of Pd2+ ion in the water samples and walnut leaf.
