title: Determination of metals by second-harmonic alternating-current voltammetry with a semi-stationary mercury electrode.
abstract: The simultaneous determination of tin(II) and lead(II) as well as of indium(III) and cadmium(II) by second-harmonic a.c. voltanunetry using a semi-stationary mercury electrode with a drop-time of 240-300 sec (the long-lasting sessile-drop mercury electrode) has been investigated. Under the best experimental conditions, concentration ratios in the ranges l:12 c(Sn):c(Pb) 15:1 and 1:15 c(In):c(Cd) 15:1 can be determined.
