Abstract
Phenolic compounds are the major pollutants in waste water from coal and petroleum industries and their concentratlons even
go up to 7000 ppm. Treatment of such waste water has been a problem so long, since the tolerance limit for disposal is 1
pprn phenol. Investigations are carried oyt on the anodic oxidation of phenol at graphite electrode in acid and sodium chloride
media using various electrochemical techniques such as linear sweep voltammetry, cyclic voltammetry and controlled potential
electrolysis. The extent of oxidation was determined by electrolysis at controlled potential of + 0.98 V which corresponds
to final oxidation peak. In acid medium the peak heights varied quantitatively with concentration of phenol. There is a scope
of using linear sweep voltammetry as an analytical method for the estimation of phenol in acid medium
