Simultaneous Determination of Trace Amounts of Lead and Zinc by Adsorptive Cathodic Stripping Voltammetry
A selective and sensitive method for simultaneous determination of lead and zinc by adsorptive differential pulse cathodic stripping voltammetry is presented. The method is based on adsorptive accumulation of the complexes of Pb (II) and Zn(II) ions with Dopamine onto hanging mercury drop electrode (HMDE), followed by reduction of adsorbed species by differential pulse cathodic stripping voltam...
متن کاملDetermination of trace amounts of lead by adsorptive cathodic stripping voltammetry in the presence of xylenol orange
Lead forms the complexes with xylenol orange in the basic solution. An adsorptivedifferential pulse stripping method for the determination of lead is proposed. The procedureinvolves an adsorptive accumulation of lead on a hanging mercury drop electrode (HMDE) inthe presence of xylenol orange, followed by reduction of adsorbed lead by voltammetric scanusing differential pulse modulation. The opt...
متن کاملDetermination of trace amounts of thallium by adsorptive cathodic stripping voltammetry with xylenol orange.
Trace amounts of thallium(I) can be determined using adsorptive cathodic stripping voltammetry in the presence of Xylenol Orange (XO). The reduction current of the thallium(I)-XO complex ion was measured by square-wave cathodic stripping voltammetry. The peak potential was at -0.44 V vs. Ag/AgCl. The effect of various parameters (pH, ligand concentration, accumulation potential and collection t...
متن کاملSimultaneous Determination of Captopril and Thioguanine in Pharmaceutical Compounds and Blood using Cathodic Adsorptive Stripping Voltammetry
Apresentamos um procedimento altamente seletivo e sensível para a determinação simultânea de captopril e de tioguanina baseado em processo de redissolução catódica adsortiva dos complexos de Cu(I)-captopril e de Cu(I)-tioguanina em um eletrodo gotejante de mercúrio. Captopril e tioguanina foram pré-concentrados na superfície da gota do eletrodo de mercúrio usando Cu(II) como sensor e tempo de a...
متن کاملDetermination of Aminophylline by Cathodic Stripping Voltammetry
Aminophylline is determined by cathodic stripping voltammetry (CSV) in BR buffer, pH 7.5 at a hanging mercury drop electrode. The detection limit was 3x10 M after 60 s accumulation at -0.60 V versus Ag/AgCl reference electrode. The linear range demonstrated up to 5x10 M using CSV. The interference caused by some purine derivatives, anions and some metal cations on the peak current was studied. ...
