Abstract: A Method has been developed for the quantitative adsorption and spectrophotometric determination of Hg (II) by employing antimony phosphate as two component adsorbing material and Dithizone (1, 5-Diphenylthiocarbazone) as spectrophotometric reagent. Antimony phosphate was prepared, processed and characterized. Antimony phosphate found to be stable towards acids, weak bases and most of the common chemical reagents. The effect of different parameters such as time of contact, amount of absorbent etc in the adsorption of 10 μg of Hg (II) have been studied. It has been observed that 100 mg of antimony phosphate is sufficient for maximum adsorption (92.62 + 1.29 %) of 10 μg Hg (II) at pH 3.5 and contact time of 3 min. Under the optimum condition of adsorption, effect of various anions and cations in the adsorption of Hg (II) has been studied. Interfering cations has been masked by using suitable masking agent or reducing the amount of cations so as to make the process more selective. The distribution coefficient values for various cations were also evaluated.
