Abstrakt

Optimum conditions are described for the determination of 2-methyl-4,6-dinitrophenol using tast polarography (limit of determination LQ = 1.10-6 mol.l-1) and differential pulse polarography (LQ = 1.10-7 mol.l-1) at a classic dropping mercury electrode and differential pulse voltammetry (LQ = 1.10-8 mol.l-1) and adsorptive stripping voltammetry (LQ = 1.10-9 mol.l-1) at a hanging mercury drop electrode.
