A new and environmental friendly method for the rapid determination of Chemical Oxygen Demand (COD) as a measure of
organic pollution was developed. Ozone was used as an oxidizing agent in the current method. Experiment was setup in 500
mL glass bottle containing 390 mL distilled water and 10 mL wastewater sample at 31ºC. The extent of dissolved ozone reacted
with the wastewater sample was monitored through an ozone sensor. Reaction time of 60 seconds achieved good linear
correlation between the extent of ozone degradation and the wastewater concentrations. The results showed that the rate and
extent of ozone degradation are linearly proportional to the initial COD concentrations in range of 0-80 mg/L for the glucosecontaining
distilled water and canteen wastewater.
