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.
