Square-wave voltammetry was used to explore the adsorption property of cefadroxil complex with copper ions on the hanging mercury drop electrode (HMDE). By employing the adsorptive stripping voltammetric approach, a sensitive electroanalytical method for the quantitative analysis of cefadroxil antibiotic was achieved. A welldeveloped voltammetric peak was obtained in pH 10 Britton-Robinson buff...

A novel experimental method was developed to study the origin of the voltammetric response of human prostate cancer (PC-3) cell suspension as a model in consideration of the biological characters of living cells. The presence of guanine and xanthine in the cell eluent secreted by the living cells was verified by HPLC assay with a DAD system and chemometric method. Comparative studies of voltamm...

Adsorptive stripping voltammetry was used to prospect the adsorption property of montelukast sodium (MKST) on the hanging mercury drop electrode (HMDE). Through appointing the adsorptive stripping voltammetric (AdSV) process, a sensitive electroanalytical method for the quantitative analysis of MKST was accomplished. A well-developed voltammetric peak was obtained in pH 10 Britton-Robinson buff...

In this study, an application of a voltammetric electronic tongue for discrimination and prediction of different varieties of rice was investigated. Different pretreatment methods were selected, which were subsequently used for the discrimination of different varieties of rice and prediction of unknown rice samples. To this aim, a voltammetric array of sensors based on metallic electrodes was u...

This communication characterises the differential pulse voltammetric response of ultramicroelectrodes in connection with two different models.

Miconazole is reduced at mercury electrode above pH 6 involving organometallic compound formation, responsible for an anomalous polarographic behavior. The electrodic process presents a large contribution of the adsorption effects. The drug can be determined by cathodic stripping voltammetry from 8.0 x 10(-8) to 1, 5 x 10(-6) molL-1 in Britton-Robinson buffer pH 8.0, when pre-accumulated for 30...

the electrochemical behavior of a modified carbon paste electrode (mcpe) with n,n′ethylenbis(salicylideneiminato)copper(ii) complex ([cu(ii)-salen]) was investigated as a newsensor for cystein. the britton-robinson buffer with ph 5, 10% modifier in electrode, potentialscanning rate of 20 mvs-1 and puls height of 50 mv were used as the optimum condition for thedetermination of cysteine using car...

the adsorption processes of amlodipine onto hydrophilic carbon nanoparticles (emperor 2000tm) are investigated. the significant increase in voltammetric responses for pre-adsorbed amlodipine compared with those for solution confirms high affinity of amlodipine to carbon nanoparticles (possibly due to π-π stacking interaction between aromatic rings of amlodipine and surface-sulfonated carbon nan...

Voltammetric behavior of muscle relaxant dantrolene sodium (DAN) was studied and the voltammetric methods for its determination using polished and mercury meniscus modified silver solid amalgam electrodes (p-AgSAE and m-AgSAE) as well as using bismuth film electrode (BiFE, ex situ plating on GCE) have been proposed. These working electrodes represent the most commonly used alternatives to mercu...
