The chenulummescence reactlon of CIO-with H,O, m akahne solution was apphed to the determmatron of gaseous chlorme species such as Cl, and HCl m ambient au The detection htmt for Cl, was 1 ppm (v/v) and the relative standard devlatlon of fne measurements of 2 5 ppm Cl, was 3 8% Hydrocarbons, ozone, nitrogen oxides and sulphur dlonde did not interfere m the determmatron of Cl, and HCl The results obtained were m good agreement wth those obtamed by ion chromatography Keywords Chenuhunmescence, h, Chlorme, Hydrogen chlonde Poly(vmylrdene chloride), poly(vmyl chloride) and polymers of other chlormated orgamc compounds such as wrap film and plastics are widely used m dally hfe However, ultnnately most of them are dumped as trash/refuse and burnt m mcmerators to release chlorme species such as HCl and Cl, Large amounts of chlorme are used m the processes for the sterlhzatlon of tap water and waste water treatment and lugh concentrations of Cl, and HCl are released from such mdustrml plants Chlorme 1s a strong oxldlzmg agent and readdy combines wrth organic compounds to produce toxic chlormated organic compounds Hydrogen chlonde 1s a strong acid and acldlfies ram 111 Hence It IS very unportant to measure their concentrations near mcmerators and water treatment plants to elucidate the fate of these chlorme speaes and the processes of ram acldlflcatlon Correspondence to Y Maeda, Laboratory of Envmmmental Chenustry, College of Engmeermg, Umverslty of Osaka Prefecture, l-l Gakuen-cyo, Sakai 593 (Japan)
