chelating resin; bis[2-(2-benzothiazolylthioethyl)sulfoxide]; recovery; metal ions
A new chelating resin containing bis[2-(2-benzothiazolylthioethyl)sulfoxide] was synthesized using chloromethylated polystyrene as material and characterized by elemental analysis and infrared spectra. The adsorption capacities of the newly formed resin for Hg2+, Ag+, CU2+, Zn2+, Ph2+, Mn2+, Ni2+, Cd2+ and Fe3+ were investigated over the pH range 1.0-6.0. The resin exhibited no affinity for alkali or alkaline earth metal ions. The maximum adsorption capacities of the resin for Hg2+, Ag+, CU2+, Zn2+, Ph2+, Mn2+, Ni2+, Cd2+ and Fe3+ were 1.49, 0.96, 0.58, 0.11, 0.37, 0, 0.24, 0.36 and 0.25 mmot g(-1), respectively. In column operation it had been observed that Hg2+ and Ag+ in trace quantity could be separated from different binary mixtures and Hg2+ could be effectively removed from industrial wastewater and the natural water spiked with Hg2+ at usual pH.
