Abstract
Food industry is one of the most stable sectors of the global market demonstrating the annual growth of the production output, including in the walnut kernel production, with subsequent generation of waste as a result of its processing. The use of walnut shells as a material for production of sorbents is a promising method of waste disposal. The goal of this research is to evaluate the sorption capacity of walnut shells to clean surface wastewater from urban territories. The object of research was the surface wastewater from urban territories. OPTIMA 2100DV spectrometer (Perkin Elmer), pH-150MI microprocessor pH meter, and JEOL JSM-6460 LV scanning electron microscope were used during the research. The obtained experiment data have shown that walnut shells are a promising material for production of sorbents.
