Study of Detergent Removal from Aqueous Solution by Natural Absorbents

Contamination of the aquatic environment by detergents is a worldwide problem. Usually waste water treatment processes are unable to remove their chemical efficiently; therefore, more appropriate techniques must be implied. The present research investigates the application of natural absorbents for removal of detergent from waste waters. Carbonic saw dust, activated carbon, raw saw dust, pine tress fruit, Caolinite sail was used as absorbent. Anionic detergent in the form of liner alkyl Benzene Sulphonate was used in 25, 50 and 300 mg/lit Concentration. After sample preparation and additional of detergent in the above concentrations the absorption behavior was studied. The results show that equilibrium time for activated carbon was 90 minutes, saw dust activated carbon 60 min. Pine tree fruit. 45 minutes. Using activated carbon made pine tree activate carbon rcduccd detergent concentrating by %95 which equaled 1.5 gram of standard activated carbon. Caolinite and raw saw dust proved to be the least efficient. The adsorption with activated carbon followed the Frundlich isotherm characteristics and carbonic pine tree fruit was accordance with Langcmurc isotherm.
