Treatment of waste water containing emerging pollutants is always a challenge as most of the organic water contaminants are resistant to degradation using conventional techniques. Emerging pollutants are a classof compounds in the environment such as endocrinial disruptors resulting from the degradation of some organic compounds or introduction of medicine in the natural environment. One of the potential technologies in the area of removal of organic water pollutants is Advanced Oxidation Process (AOP). Free radical induced degradation is the main process involved in AOP. It is generally observed that the degradation induced by any AOP may not lead to absolute mineralisation. In the present report, various AOPs for the destruction of a number of emerging pollutants are discussed. The advantages and limitations of these technologies are highlighted. Two main AOPs, hydrogen peroxide photolysis and sonolysis, for the destruction of two model pollutants such as fensulfothion and atenolol are presented. Kinetics of the reaction, extent of mineralisation and the details of the products are also presented.
