A catalytic spectrophotometric method for the determination of trace amounts of bromide is proposed. In acidic solution 4,4'-bis(dimethylamino)diphenylmethane (tetrabase) is oxidized by chloramine T to form a blue compound, which is further oxidized to a greenish-yellow compound. The reaction is acc
