OPTIMIZATION OF PARAMETERS FOR CATIONIC SURFACTANT REMOVAL FROM DOMESTIC WASTE WATER BY ACTIVATED CORN COB POWDER

Direct and indirect releases of large quantities of surfactants to the environment may result in serious health and environmental problems. Therefore, surfactants should be removed from water before water is released to the environment. Using powdered activated Corn cobs as adsorbent may be an effective technique to remove surfactants. In this study, the removal of surfactants by adsorbent was investigated and the influences of the operating parameters on the effectiveness on adsorption rate were studied. Cetyl trimethyl ammonium bromide (CTAB) has been widely used in synthesis of gold nanoparticles (e.g., spheres, rods, bipyramids), mesoporous silica nanoparticles (e.g., MCM-41), and hair conditioning products. The present research work is to investigate the optimized conditions for removal of cationic surfactant from domestic waste water using activated Corn cob powder .The initial concentration of cationic surfactant in domestic waste water is 426ppm. The optimum conditions for removal of cationic surfactants were Time of 90min, Adsorbent dosage of 1%(W/V) , pH-7 and at 30℃ temperature obtained. From the obtained optimal conditions the removal efficiency was 90.6 % .
