Abstract :Water is an important of life. When it is polluted, it disturbs not only human but also aquatic life. There are no of chemicals that contaminate the water. Industries generate different types of chemicals, which pollute the water. Effluent from these industries contains heavy metals, BOD, COD and phenolic compounds. Water pollution is a very serious issue. Different ways are available to treat the waste water. Flocculation, sedimentation, coagulation, photolysis and electrochemical methods are used for treatment of waste water. Phenolic compounds are the most harmful chemicals present as contamination in waste water. Phenolic compound accompanied with chlorine can exist as mono-chlorophenol, di-chlorophenol and tri-chlorophenol. These compounds are very carcinogenic in nature so their presence is dangerous for human as well as aquatic life. In this research electrochemical method is used to treat o -chlorophenol. Effect of electrodes, voltages and treating times on the removal efficiency have been studied. Stander sample of 100ppm from stock material have been prepared as an analogues to the waste water of industries. HPLC/UV detector is used to analyze the treatment effects. Graphite electrode, 20 volts and 20 min operating time is the most effective parameters that removes about 60% of the initial concentration of 2-CP (ortho-chlorophenol).
