Abstract

Background and Objectives: The presence of chemical dyes in the water resources not only pollutes them, but also brings about death of organisms and serious indemnities to the environment through stopping oxygen production and preventing penetration of the sunlight. In this study, we investigated the efficiency of the ELECTROLYSIS process for DECOLONIZATION of PHENOLPHTHALEIN and PHENOL RED from aqueous environment.Materials and Methods: The experiments were conducted in an electrochemical reactor having a working volume of 1 liter equipped with 2 graphite electrodes. This study was conducted at laboratory scale. Samples were prepared by dissolving two PHENOL RED and PHENOLPHTHALEIN dyes in drinking water. Then, the effect of operating parameters such as voltage, inter-electrode distance, and NaCl concentration on the complete dye removal was determined considering optimum retention time using Factorial variance analyses and the graphs were plotted using MS Excel software.Results: the results showed that the optimum conditions for completely removal of PHENOLPHTHALEIN was achieved applying a voltage of 48 V, the retention time of 9 minutes, 5 cm inter-electrode distance, and the salt concentration of 1.5 g/l, whereas, complete removal of PHENOL RED was achieved applying a voltage of 48 V, the retention time of 8 minutes, 5 cm inter-electrode distance, and the salt concentration of 2 g/l. Under these conditions, COD removal efficiency for PHENOL RED and PHENOLPHTHALEIN was 85 and 80 percent respectively.Conclusion: This study revealed that ELECTROLYSIS process is an effective method to remove both PHENOLPHTHALEIN and PHENOL RED dyes from effluent, because it can completely remove the dyes in a short time.
