Abstract
A method was developed for the analysis of total organic chlorine and bromine compounds (TOCl, TOBr) in water samples. The method is based on the adsorption of organic compounds on specially prepared activated carbon. Neutron activation analysis (neutron flux 4·1012 n cm−2 s−1) was used for the quantitative determination of chlorine and bromine.
The factors investigated were the adsorption of organic chlorine and bromine compounds on activated carbon, the effect of pH on the adsorption, the removal of chlorine ions from activated carbon by nitrate washing, the amount of activated carbon required, the adsorption time, the potential number of successive adsorptions and the preservation of samples.
The detection limits for TOC1 and TOBr were 5 and 0.5 μg 1−1, respectively, when the sample size was 100 ml.
