Abstract:

A simple and precise spectrophotometric method coupled with solvent extraction is used for determination of trace concentration of Pd(II) using Hexane-2,5-dione-bis-(ethylenediamine) as a novel analytical reagent. The reagent forms a stable pink complex which is quantitatively extracted at pH 3.5. The absorption spectrum of Pd:HDBE complex in chloroform exhibits absorption peak at 474 nm. Beer's law is obeyed in the range of 2- 20 ppm. Molar absorptivity & Sandell sensitivity calculated as 0.750x104 L mol-1cm-1 and 3.6x10-5µg cm-1 respectively. Stoichiometric ratio of Pd:HDBE was 1:2 ascertained by Job's method, mole ratio method and slope ratio method . Effect of diverse ions is also reported. The newly proposed method is applied for estimation of Pd at trace level.
Key words : Hexane-2, 5-dione-bis(ethylenediamine), absorption spectrum, diverse ions.
