Abstract
Bromine is produced on-line in a flow injection system by injection of acid into neutral or slightly alkaline bromate - bromide eluent and is determined voltammetrically at a glassy carbon electrode. Organic compounds that can be brominated or oxidised by bromine are determined by injecting them, in acidic solution, into the bromate - bromide eluent and noting the decrease in the bromine signal. Determinations can also be made by injecting pre-reacted solutions of bromine and the organic compounds in order to monitor the excess of bromine.Keywords
