Abstract

Abstract: Polychlorinated biphenyls (PCB) are persistent organic pollutants used worldwide up 1990s. Although their use has been heavily restricted, PCB can be found in contaminated soils and sediments. Conducted structural-chemical studies of the destruction of polychlorinated biphenyl salts of amino acids in the soil. The effect of concentrated solutions of sodium salts of amino acids on soil particles has been investigated using FTIR spectroscopy as a means of identifying PCBs in the soil, controlling the interactions of PCBs with amino acid salts. The reaction products —C— substituted biphenyl polyamino polyacetic acids and their salts are soluble in water and extracted from particles on the surface of which polychlorinated biphenyls are adsorbed.
