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).
