Abstract: Background: Chlordane has been used for many years as an insecticide and it is stable against light under normal conditions. The aim of this study was to determine the Nano-photocatalytic activity of UV / Fe-Doped TiO2 for removal of cis-chlordane from water. Materials and Methods: This descriptive-analytic study, was conducted at the laboratory scale in a 2-liter reactor. The nanoparticles were synthesized by sol-gel method. Cis-chlordane analyzed in a variety of pH, time, and concentrations. Excel 2007 and SPSS V.16 softwares and ANOVA test were used for data analysis. Results: The results showed that in the conditions of low pH, low concentration of pesticide, high concentration of Nano particles, and high contact time, the removal efficiency will increase. The optimum PH to remove cis-chlordane, in constant time and Nano-particle concentration, was equal to 5 (P value = 0.324). The optimal time for Cis-chlordane removal was revealed to be 45 minutes (P value = 0.112) and the nanoparticle concentration for optimal removal was 100Mg/L (P value = 0.069). In addition, optimal cis-chlordane removal occurred in cis-chlordane concentration of 10 Mg/L (P value = 0.2). Conclusion: The photo catalytic processes have high capacity to remove cis-chlordane and toxic minerals. Titanium dioxide nanoparticles are non-toxic and UV/Fe-Doped TiO2 can be used to degrade cis-chlordane efficiently with the small amount of Nano-materials and very low power consumption. Key words: cis-chlordane, photocatalytic degradation, Nano photocatalyst, Fe-doped TiO2
