Abstract:n this paper the authors studied the conditions for the determination of trace phenol by KBrO3KBr and UV spectrophotometry in the presence of hydrochloric acid.Based on this technique a new method for the determination of trace phenol was established.It is shown that the linear range and apparent molar absorptivity and sandell index are 0.102.5mg/L and 1.89104 Lmol-1cm-1 and 4. 98g/cm2 respectively for the determination of phenol in 0.6mol/L HCl ,310-5mol/L KBrO3,510-4mol/L KBr,610-4mol/L KI solution.This method has been used to determine phenol in sewage.
Keywords:KBrO3-KBr  I2
