Abstract

A study was carried out of the polarographic behaviour of the genotoxic substance 1-(2’-carbamoylphenyl)-3,3-dimethyltriazene and optimum conditions were found for its determination by tast polarography or differential pulse polarography at a static mercury drop electrode and by fast scan differential pulse voltammetry at a hanging mercury drop electrode in the concentration range 1 . 10<sup>-4</sup> -2 . 10<sup>-7</sup> mol 1<sup>-1</sup>. The sensivity of the determination can be further improved through adsorptive accumulation of the test substance on the surface of the hanging mercury drop electrode; five-minute accumulation in unstirred solution permits determination in the concentration range (2-10 . 10<sup>-8</sup> mol 1<sup>-1</sup> and two-minute accumulation in stirred solution allows determination in the range (2-10) . 10<sup>-9</sup> mol 1<sup>-1</sup>.
