AMPEROMETRIC TITRATION OF MERCURY (II) WITH MPCMDEDTC SOLUTION IN DIMETHYL SULFOXIDE
. The article studies the voltammetric behavior of 4-methoxyphenyl carboxymethyl diethyldithiocarbamate (MPCMDEDTC) in dimethyl sulfoxide (DMSOn the presence of background electrolytes with different acid-base properties in the anodic polarization region of a platinum microdisk electrode. MPCMDEDTC is oxidizied in 0.125 M LiClO 4 solution forming one clearly pronounced anode wave with E1 /2 = 0.85 V, while the wave height varies in proportion to the concentration of the depolarizer. A procedure has been developed of amperometric titration of mercury (II) with a standard MPCMDEDTC solution in DMSO using two indicator electrodes.
