A study was made of the polarographic behaviour of the genotoxic substance 1-(4′-bromopheyl)-3,3-dimethlytriazene and optimum conditions were found for its determination by tast polarography and differential-pulse polarography at a static mercury drop electrode in the concentration range 1 × 10-4-1 × 10-7 mol dm-3. The results indicate that the method can be used at pH between 4.5 and6.0 for the identification and determination of the investigated substance, which is protonated without decomposition in this pH range. It was established that for the reduction of the NN group four electrons are required and the resulting products are 4-bromoaniline and dimethylhydrazine.
