Anolyte Solution Generated from Electrochemical Activation Process for the Treatment of Phenol

Studies on the treatment of an aqueous solution of phenol using anolyte solution generated from electrochemical activation process were carried out. The aim of the studies is to investigate the effectiveness of anolyte solution in treating 100, 200, and 500 mg/l of phenol in water solution. Kinetic parameters, such as reaction rate constant (k) and order of reaction (n) should be studied to determine rate of degradation of phenol by anolyte solution. The treatment was carried out on batch experiment. The experimental procedures consist of five series of experiments. The first series is to study the effects of voltage current on the production of anolyte solution. The aim of the studies is to determine an optimum condition of voltage current to produce anolyte solution. The second series is to study the characteristics of anolyte solution. The aim of studies is to determine the composition of anolyte solution. The third series is to investigate the effects of the addition of anolyte solution in treating 100 mg/l of phenol. The fourth series is to investigate the effects of initial concentration of phenol. The aim of the experiment is to propose mechanisms and kinetic rate degradation of phenol by anolyte solution. The last series is to investigate the effects of initial pH of sample on degradation of phenol. Based on decreasing concentration of phenol and the consumption of chlorine, chloride, and chlorine dioxide, as well as the production of carbon dioxide, the effects of anolyte solution in the treatment of phenol have been obtained. The mechanisms and kinetic rate degradation of phenol have been also proposed well. The kinetic rate constant degradation of phenol has been found at 0.017269 for initial concentration of phenol 100 mg/l. And the removal of phenol by anolyte solution is more likely achieved in acid condition. This is because chlorine is slight effective to react in acid.
