Polarographic and voltammetric determination of trace amounts of 9-nitroanthracene

Optimum conditions have been found for the determination of carcinogenic 9- nitroanthracene by tast polarography in the concentration range of 1 x 10(- 4)-1 x 10(-6) M, differential pulse polarography at a dropping mercury elec trode in the concentration range of 1 x 10(-4) 2 x 10(-7) M. differential p ulse voltarnmetry at a hanging mercury drop, electrode in the concentration range of 1 x 10(-5)-2 x 10(-7) M and adsorptive stripping voltammetry in t he concentration range of 1 x 10(-7) -2 x 10(-9) M. The applicability of th e newly developed methods in combination with solid phase extraction was ve rified using real samples of drinking and river water.
