Abstract :

Environmental pollution is one of growing worldwide problem, especially, drinkable water is threaten by heavy metals in process of industrial growth. To solve this issue, all technique including membrane filtration, chemical precipitation ionexchange, has been tired, Among them, adsorption materials are very simple and cost-effective. The Mesoporous polymers with 2-50nm pore size are one of most promising subject in wastewater treatment. Because it provides not only low diffuse barrier for water but also possibility of post-modification. Herein, we synthesized polyaminal polymer with Melamine and monomer based on benzenealdehyde which have hierarchical structure with 400~650m2/g BET surface area. Then decoration of sulfur and nitrogen on designed polymer with thiol-yne click chemistry. Thiol yne click reaction is very reactive under UV lamp. In this study, designed MVP-SN investigated by BET,ICP-OES, Elemental analysis, SEM, EDAX for evaluating of heavy metal removal such as Cd(II), Pb(II),Hg(II) and Cu(II) . Recent Publications: 1.
