A sensitive method for the determination of vitamin \(\mathrm{K}_{3}\) using cathodic stripping voltammetry is presented. Using sodium sulfate as the supporting electrolyte at \(\mathrm{pH} 1.70-1.85\), a reductive peak ( \(-0.64 \mathrm{~V}\) vs SCE) is observed. The detection limit is \(1 \times 1
A cathodic stripping procedure has been developed for the determination of mebendazole. An 8 min accumulation time on a 0.1 M acetic acid/acetate pH=5 buffer solution gives rise to a detection limit of 3 x lo-l1 M. An extraction with ether has been developed for the determination of mebendazole in u
Germanium(W) can be determined using adsorptive cathodic stripping voltammetry in the presence of 3,4-dihydroxybenzaldehyde (DHB). The sensitivity of the voltammetric technique was improved greatly by the addition of vanadium(W) to the sample. The reduction current of the adsorbed germanium(W)-DHB c
