摘要
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.
