Extractive Spectrophotometric Determination of Pd(II) with Sodium Salt of Hexamethyleneiminecarbodithioate

Full Text PDF

Abstract:

The reagent NaHMICdt·2H2O has found to be a good chelating agent for the spectrophotometric determination of various metal ions. The present investigation deals with spectrophotometric determination of Pd(II) by using NaHMICdt·2H2O. The reagent reacted with Pd(II) to give yellow complex extractable into toluene. Pd (II) was extracted quantitatively in the pH range 0.5-2.0. Pd(II)-HMICdt complex showed λmax at 435 nm. The extracted species has a 1:2 (M:L) stoicheometry. Beer’s law is obeyed in the range of 0.2-0.8 μg ml-1 of Pd (II). The molar absorptivity and the sandells sensitivity were found to be 0.754 x 104 lmol-1cm-1 and 0.0140 μg mol-1 cm-2 respectively. The effect of divers ion on the extraction of Pd(II) has been investigated. The proposed method is highly sensitive, selective, and simple and rapid has been applied for accurate determination of palladium in synthesis mixtures and real samples.
