Sažetak
Development of low-cost bioadsorbents produced from various waste biomass became the focus of many research studies due to their eco-friendly, sustainable and high efficiency removal of heavy metals, nutrients, pesticides, dyes and similar pollutants removal from water and wastewaters by adsorption. Waste biomass obtained from agriculture or the food industry is especially interesting since those materials are usually cheap, available in large quantities during the whole year and harmless. In most cases, the adsorption capacity of those biomaterials can be increased by chemical modification. In this study three various lignocellulosic waste biomass produced by food industry: pumpkin peel, cocoa bean shell and sunflower shell were chemically modified in other to increase adsorption capacities of named biosorbents by quaternization reaction using N, Ndimethylformamide and epichlorohydrin (ETM method). Obtained bioadsorbents and their base materials were structurally characterized in order to determine the content of following elements: C, O, N, Cl, Nb, Rh, Zr, Cu and Rb by energy-dispersive X-ray spectroscopy (EDS). The surface structures and morphology were examined using Field Emission Scanning Electron Microscope (FE SEM) while a high-resolution tool Transmission Electron Microscope (TEM) was used to analyze atomic arrangement.
