Abstract

Introduction: Surfactants or surface active agents are organic chemicals that accumulate at the interface gas-liquid or liquid Wax, change the properties of water by reducing the surface tension of water, they speed up the cleaning process.Direct discharge of raw sewage or treated effluent, detergents into the environment and pollution, water resources and rising costs are reduced in quality. The purpose of this study is to evaluate the performance of Leca-containing TITANIUM DIOXIDE nanoparticles for the removal of the surfactant from WASTEWATER.Methods: This study is an experiment one at which batch experiments were performed using a Photocatalytic reactor. To study the preparation and properties of catalytic adsorbent Leca to increase the efficiency of TITANIUM DIOXIDE (Tio2) was used. Parameters (3, 5, 7, 9, 11) pH, amount of adsorbent (0.25-2 g/L), surfactant concentration (25-200 mg/L) and contact time (15-120 min) was evaluated by Leca- corrective Adsorbent. Experiments on synthetic examples and in optimal conditions, on real samples were also performed. Surfactant concentration is measured with a spectrophotometer model (shimadzu UV-1800) was performed at a wavelength nm467.Results: The maximum removal of surfactant through Leca- modified in aqueous solutions of synthetic SDS in optimal conditions (contact time 30 min, pH=5, the value of 1 g/L of adsorbent and initial concentration of surfactant is 100 mg/L) at a rate of 98% in the same samples the actual result was 87%. The process of adsorption followed second-order kinetic model and the adsorption isotherm data (R2=0.984) was more consistent.Conclusion: The results showed that the Leca-containing nanoparticles of TITANIUM DIOXIDE can be used as an effective adsorbent for the removal of ANIONIC SURFACTANTS from aqueous solutions used.
