AbstractThe pollution becomes more serious with the development of economy in China especially for waste water, among which 80% comes from industries. The absence of fresh water has large limitation to the development of China now. Because it will bring the most harmful results to environment and health of people, the degradation of POPs is very important. Radiation is one of the effective methods for mineralization of POPs as most of their compounds are derivatives of phenyl ring. However, the costs of equipment and operation are too high to use for irradiation. It should be supposed that breakage of benzene ring of POPs at lower irradiated dosage (below 20 kGy) in developed radiation processing turns into organic acids and other compounds, which could be removed by micro-organisms easily. It means that after irradiation organic materials can be treated by the use of biological method. It is obvious that integration of different processing could both use the advantage of breaking phenyl ring under lower dosage and overcome the disadvantage of reducing the TOC at very high dosage by use of irradiation. In this paper, the radiolytical mechanism of 4-chlorphenol as a model of POPs has been studied by the use of pulse radiolysis and analysis of stable products irradiated in different conditions. It has been shown that 4-chlorphenol can be turned into organic acids effectively in basic aqueous solution saturated with oxygen under lower irradiated dosages. (c) 2005 Elsevier B.V.
