Treatment of Phenolic and Aromatic Amino Compounds in Polluted Waters by Photocatalytical Oxidation

Abstract Improper handling of rocket fuel residues at abandoned military bases has resulted in heavy pollution of the soil and groundwater with aromatic amino compounds. A similar phenomenon is observed with ash dumps in which solid waste from oil shale thermal treatment is disposed: the ash dump leachate is heavily polluted with phenolic and other compounds, resistant to biological treatment. Experimental research of photocatalytical oxidation (PCO) of both classes of substances and polluted waters was undertaken. The influence of different parameters - pH, concentration of substances to be oxidised, character of substances formed during the PCO, presence of inorganic admixtures, effect of OH
