The affect of water quality on corrosion inhibition of aqueous ozone has been investigated systematically.The water quality indexes investigated includes hardness, alkalinity, pH, temperature, Cl-, SO42-, CODCr, SS and TDS.The experiments show that good corrosion inhibition can be achieved and the water quali- ty has great effect on corrosion inhibition ratio in aqueous ozone.The affect of hardness is much greater and aqueous ozone shows much better effect on corrosion inhibition while the hardness is 200～ 300 mg/ L.The ratio of corrosion inhibition decreases while the temperature of the solution goes up and/or the concentrations of SS, SO42-,Cl-and TDS increase.
Key words： water quality index; ozone; corrosion inhibition
