Electrochemical determination of mercury (II) with a mfcmdedtk solution in the medium of dimethylpharmamide

Abstract

AbstractThe article studies the voltammetric behavior of MPCMDEDTC in dimethylpharmamide (DMF) in the presence of background electrolytes of different acid-base properties in the anodic region of polarization of a platinum microdisk electrode. MPKMDEDTC is oxidized against the background of 0.125 M lithium perchlorate, forming one clearly pronounced anodic wave with E1/2 = 0.85 V, while the wave height changes in proportion to the depolarizer concentration. Amperometric titration of mercury (II) with two indicator electrodes with a standard solution of MPKMDEDTC in DMF medium is proposed.
