✦ Synopsis

In this paper the relative advantages of usmg square wave adsorptive smppmg voltammetry m combmatlon Hrltb a mercury film electrode as the workmg electrode were assessed It was found that the resultmg techmque IS fast, sensltwe, offers excellent d wnrmnatmn agamst the background current and can be used w&out deoxygenation of the sample, the analytical apphcations of the technique are demonstrated for the determmatlon of Nl(II) with a lnmt of dete&on of 0 85 nmol l-' and a lmear range of 3 orders of magmtude (for 60 s preconcentration) and for the determmatlon of Cu(II) m the mnol 1-l concentration level m the presence of dissolved oxygen Kkyworuk Strrppmg voltammetry, Mercury film electrodes
