| The water sample is acidified with nitric acid to pH < 2. The organohalogen compounds are taken out of the water by shaking the sample with active carbon. The inorganic halogens are washed out by flushingwith an acidified sodium nitrate solution. Combustion of the hydrohalogens takes place in an oxygen flow. Absorption of the hydrohalogens is followed by the determination of halogen ions by means of micro-coulometry. The result is expressed as mass concentration of chloride. |
