Abstract

Surface active agents are organic chemicals that reduce surface tension in water and other liquids. The most familiar use for surfactants are soaps, laundry detergents, dishwashing liquids and shampoos. Other important uses are in the many industrial applications for surfactants in lubricants, emulsion polymerisation, textile processing, mining flocculates, petroleum recovery, wastewater treatment and many other products and processes. here are many sources of surfactants that are discharged into natural waters. Industrial sources include textile, surfactants and detergent formulation. Surfactants are also used in laundries and households and are therefore found in discharges from sewage treatment works. They also have agricultural applications in pesticides, dilutants and dispersants. Need to study the content of surface active agents in water objects specifying their type and research chemical water self-purification processes in the presence of such substances.
