Adsorptive 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 secnidazole in urine by adsorptive stripping voltammetry.
Cyclic voltammetry was used to explore the adsorption behavior of secnidazole on a hanging mercury drop electrode (HMDE). The effects of various operational parameters on the accumulation behavior of the adsorbed species were tested. Thus, a sensitive stripping voltammetry procedure for the determination of secnidazole with an adsorptive accumulation on the surface of HMDE has been developed. M...
متن کاملAdsorptive stripping voltammetric methods for determination of aripiprazole
Anodic behavior of aripiprazole (ARP) was studied using electrochemical methods. Charge transfer, diffusion and surface coverage coefficients of adsorbed molecules and the number of electrons transferred in electrode mechanisms were calculated for quasi-reversible and adsorption-controlled electrochemical oxidation of ARP at 1.15 V versus Ag/AgCl at pH 4.0 in Britton-Robinson buffer (BR) on gla...
متن کاملAdsorptive 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 ultra trace of thiosemicarbazide by adsorptive stripping voltammetric method
In the present work, an adsorptive stripping voltammetric method using a hanging mercurydrop electrode (HMDE) was described in order to determine the ultra trace of thiosemicarbazidein different real samples. The method is based on accumulation of thiosemicarbazide on mercuryelectrode. The potential was scanned to the negative direction and the differential pulse strippingvoltammograms were rec...
