The generation of hazardous industrial effluents is a serious problem experienced by nations throughout the world. There remains however, a need for new processes to reduce the overall environmental impact of industrial synthetic chemistry. The problem of effluent generation may be approached in two manners. Firstly new production technologies could be adopted which could reduce effluent generation by adopting catalytic processes, which are non-polluting. The other approach would be the application of novel waste treatment technologies. Techniques such as photocatalytic and adsorption have...
