  7. Abstract:
  8. Nanotechnology as an interdisciplinary science is used in many fields. The use of nanomaterial, make new opportunities in the industry. However, safety issues and environmental risks of the consequences of their use in various applications are the matters of concern. Because of the new emergence of this technology, it is essential that all aspects including possible harmful effects on the environment will also be considered. One way to remove the nanoparticles, is electrocoagulation method, assemble nanoparticles into larger particles with an electric current. In this study, the removal of titanium dioxide nanoparticles, due to its high use in the industry, with electrocoagulation method and the influence of time, voltage, initial concentration of nanoparticles and pH by the response surface experimental design method, are discussed. The reactor have been used include 6 aluminum and iron electrodes spaced 2cm in monopoles way. Synthetic wastewater containing titanium dioxide nanoparticles completely dispersed in deionized water was used. The results showed that electrocoagulation process is an effective method for the removal of nanoparticles and nanoparticle concentration, pressure and pH had the most effect on the efficiency. The optimum conditions for the efficiency of 100% by the model, was calculated. (voltage = 10/5 V, pH = 7/5, time = 52 min, the initial amount of nanoparticles of titanium dioxide 0/08 grams equal to concentration 40 ppm) that match the empirical efficiency reached in optimal conditions (%99/328). In these circumstances turbidity removal efficiency was achieved %87/24
