DETERMINATION OF ULTRA-TRACE AMOUNTS OF COBALT BY ADSORPTIVE DIFFERENTIAL PULSE VOLTAMMETRY USING ACDA (2-AMINOCYCLOPENTENE- 1-DITHIOCARBOXYLIC ACID)
The present work describes a selective, rapid and sensitive method for the determination of cobalt using the adsorptive differential pulse voltammetry technique. The method is based on the accumulation of Co(II) complex with 2-aminocyclopentene-1-dithiocarboxylic acid on a hanging mercury drop electrode, followed by measurement of the current of the adsorbed complex. The effects of experimental...
متن کاملDetermination of Tl(I) Ions in Homeopathic Drugs by Differential Pulse Anodic Stripping Voltammetry
Objectives: The present study is focused on the determination of thallium (I) ions in homeopathic drugs. Methods: The determination was carried out using the Differential Pulse Anodic Stripping Voltammetry (DPASV) technique coupled with the flow-injection measuring system (FIA-DPASV). Results: The thallium content was analyzed in two commercial homeopathic preparations (Thallium aceticum 5CH an...
متن کاملDetermination of Trace Amounts of Nickel by Differential Pulse Adsorptive Cathodic Stripping Voltammetry Using Calconcarboxylic Acid as a Chelating Agent
A method for the determination of nickel(II) by stripping voltammetry is described. The method is based on the adsorptive accumulation of nickel(II) calconcarboxylic acid complex onto a hanging mercury drop electrode (HMDE), followed by the reduction of the adsorbed complex using differential pulse voltammetry. The optimum operating conditions and parameters were found to be 0.05 M NH3/NH4Cl bu...
متن کاملAnodic stripping voltammetry of trace metals by batch injection analysis
The application of batch injection analysis to the determination of trace metals in samples of volume s 100 ~1 by square wave anodic stripping voltammetry has been investigated in detail, using a programmable electronic micropipette. The in situ formation of a mercury film on a glassy carbon electrode substrate, the influence of preconcentration time, injection rate and injected volume of analy...
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...
