ABSTRACT: Tin and its
derivatives are extensively used in modern technology tools which lead
requirement for development of green methods for its waste management and profitable
recycling. Presence of tin in water bodies causes enormous environmental
concern due to its acute toxicity to living beings. We demonstrate a simple and
zero emission process for extraction of tin ions from aqueous solution using
dithiocarbamate-based copolymer and its single step quantitative recovery and
transformation into SnS nanoparticles. The polymer shows high metal extraction
capacity, 1.06 g SnCl2 per gram of polymer. The polymer metal
composite and SnS nanoparticles are analyzed using TEM, FTIR, XRD spectroscopy
techniques. The FTIR shows formation of Sn-S bonding in the polymer metal
composite. This study has implication for cost effective and green approach for
purification of water and waste management.
