A validated stripping voltammetric procedure for quantification of the anti-hypertensive and benign prostatic hyperplasia drug terazosin in tablets and human serum

Validated Polarographic Methods for the Determination of Certain Antibacterial Drugs

“…Adsorptive stripping voltammetric analysis is an extremely simple and sensitive technique that can be used for the analysis of drugs without the necessity for extraction steps prior to the assay. In continuation of previous work on the use of electrochemical methods for drug analysis, 25 and our previous work on fluoroquinolones, 26,27 the present investigation deals with an electroanalytical method for determination of LFX, SFX, GFX, and MFX.…”

Ionic Liquid Crystals Modifier for Selective Determination of Terazosin Antihypertensive Drug in Presence of Common Interference Compounds

“…Furthermore, the pKa of TZ is 7.1, therefore it is positively charged at the working pH (7.40) [23]. SDS can be adsorbed on the electrode surface forming a layer with highly dense negatively charged ends pointed outside the electrode.…”

“…Electrochemical methods have received considerable interest due to their higher selectivity, lower detection limit, lower cost and faster operation than other reported methods [21,22]. Since the innovation of carbon paste electrodes (CPEs) by Adams, they have been widely used in many fields such as voltammetry, amperometry and potentiometry [23].…”

“…The ease and speed of preparation and of obtaining a new reproducible surface, low residual current, porous surface, and low cost of carbon paste are some advantages of CPE over all other carbon electrodes [23][24][25][26].…”

Validation of a tubular bismuth film amperometric detector

“…Mercury electrodes, most notably the mercury drop electrode (MDE) [1,2], the hanging mercury drop electrode (HMDE) [3,4] and mercury film electrodes (MFE) [5,6], have been commonly employed for this purpose. The main disadvantage of these electrodes, which is becoming increasingly important in our environmentally conscious world, is the extreme toxicity of the mercury and mercury salts employed in their preparation.…”
