IDENTIFICATION AND DETERMINATION OF ORGANOHALOGEN COMPOUNDS IN SWIMMING POOL WATER

Volatile organohalogen compounds were determined in a swimming pool us ing three methods: determination of volatile organic halogen (VOX) aft er sorption on XAD solid sorbent, thermal desorption and coulometric t itration of the halides formed; identification and determination of th e individual organohalogen compounds after sorption on XAD-4, solvent extraction and chromatographic determination; direct injection of aque ous samples to the chromatographic column. The concentration of organo halogen compounds varied from 35.9 to 99.7 mug/dm3 for trichloromethan e, 22.0 to 57.7 mug/dm3 for dichloromethane, 2.4 to 27.4 mug/dm3 for t richloroethylene, 2.3 to 14.7 mug/dm3 for bromodichloromethane and 4.2 to 7.6 mug/dm3 for tetrachloromethane. The results obtained by the th ree methods are consistent in principle.
