| Popis: | Water pollution is a complex problem as the removal of various pollutants along with microbes need multifunctional materials to make the polluted water potable. Selective removal of highly toxic pollutant such as Hg2+ ions from wastewaters is an area of critical significance. In this study we report a bi-functional material derived from N-vinylformamide (NVF) that is highly selective and has high adsorption capacity for Hg2+ ions with qm of 248.76 mg g−1 and it also acts as an biocidal agent against the representative microorganisms Gram (+), S. epidermidis, Gram (−) S. typhi, bacteria and a fungus C. albicans. The effect of different parameters as well as that of the competing ions on Hg2+ ions adsorption capacity was studied. The material reported in this article represents an important advance over the earlier reported materials. |
