Domestic waste water is one of the important pollution sources affecting the water quality adversely in many developed countries.Especially waste waters containing detergents are among the basic constituents of organic pollutants and they cause great environmental damages by introducing into the soil,sears,lakes and rivers.Detergents are the mixtures of surfactants and their isomers and preferred to soap because of their many superior properties.As a result of economic development and population growth,environmental problems caused by detergents are increasing day by day.Surfactants can not be biologically degraded and become abundant into water bodies from domestic and industrial waste waters.This damages the natural balance of waters,threatens the health of aquatic organisms and humans who feed on them.For example linear alkylbenzene sulfonate(LAS)is a surfactant and is found in high amounts in domestic and industrial waste waters discharged from textile,leader,food,paint,polymer,cosmetics,mining,oil recovery and paper industries(1).
