Original Abstract

Ozone was generated by commercial ozonizer Lifetech with production efficiency up to 0.5 g of ozone per hour. Both technical and synthetic air (mixture of nitrogen and oxygen 80:20) with gas flow varying from 0.3 to 1.8 L/min was used for ozone production. Absolute ozone concentration was determined by iodometric titration and by spectrophotometry of oxidized iodine solution. Selected metal materials (iron, stainless steel, copper, brass and aluminium) in the form of hollow tubes were placed in Pyrex glass reactor during the experiment. Changes of ozone concentration produced at different experimental conditions (reaction time, input power, gas flow rate, gas composition) were compared with respect to the used material.
