TY - JOUR TI - Study of polylysine and chitosan nanoparticles synthesized using various cross-linkers and their applications for heavy metal ion recovery DO - https://doi.org/doi:10.7282/T3377C13 PY - 2016 AB - Nanotechnology offers the possibility of an e ective and efficient removal of pollutants from waste water. This removal of pollutants and heavy metal ions is being accomplished using nanoparticles, nanomembranes and nano powders of various materials. Chitosan, a polysaccharide, and polylysine, a polypeptide, have been receiving increasing attention for their metal scavenging and sequestering properties. One part of this study focused on synthesizing nanoparticles of polylysine, chitosan and mixed chitosanpolylysine nanoparticles using various cross-linkers involving ionic and covalent interactions. The effect of pH on the type of bonding between polymers and cross-linkers as well as the properties of nanoparticle suspensions were studied. Nanoparticles synthesized were characterized based on their size and zeta potential using dynamic light scattering techniques. Second part of the study focused on using these nanoparticles for adsorbing copper from aqueous solutions and analyzing the amount of adsorption using NMR spectroscopy technique.
