Adsorptive stripping voltammetry - A new electroanalytical avenue for trace analysis
nickel can also be determined using a copper anode. Conditions are similar to those for nickel except that the applied potentials must be 200 mV more positive than for nickel. The anodic reaction rate constants with copper are typically somewhat greater than with nickel, however the applied potential results in increased background noise so that copper offers no signal-to-noise advantage over n...
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 کاملAdsorptive Stripping Voltammetry in Lipophilic Vitamins Determination
The aim of this contribution was to check if adsorptive stripping differential pulse voltammetry (AdSDPV) is suitable tool for sensitive simultenous electrochemical detection of lipophilic vitamins. Retinol (vitamin A1), cholecalciferol (vitamin D3), α-tocopherol (vitamin E) and phylloquinone (vitamin K1) were selected as representatives. All electrochemical measurements were performed in two s...
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...
