Abstract
A study of the atmospheric sampling of the haloforms trichloromethane bromodichloromethane, chlorodibromomethane and tribromomethane is presented. Under conditions of high humidity the efficiency with which the haloforms can be collected on activated carl is both poor and irreproducible. Desiccation of the atmosphere with sodium hydroxide effectively improves sampling efficiency without significant haloform loss and can be readily applied to field sampl1ng The performance of charcoal sampling tubes under a range of conditions is investigated and sutaible conditions for the collection and analysis of chlorinated and brominated haloforms are described.This publication has 3 references indexed in Scilit:
