Preconcentration of tranquilizers by adsorption/extraction at a wax-impregnated graphite electrode

Promethazine determination in plasma samples by using carbon paste electrode modified with molecularly imprinted polymer (MIP): Coupling of extraction, preconcentration and electrochemical determination

“…Electrochemical methods such as differential pulse polarography [29], voltammetry [30][31][32][33][34][35][36][37][38][39], potentiometry [40,41], and amperometry [42,43], have been widely applied for the determination of promethazine.…”

“…As for the evaluation of the electrochemical behavior and quantification of promethazine by electroanalytical techniques, several electrodic surfaces such as glassy carbon electrode [31,32], gold electrode [2] and electrodes modified with carbon nanotube [35], wax impregnated graphite electrode [30], highly boron doped diamond [37] and modified carbon paste electrode [34] have already been used as working electrodes.…”

Determination of clozapine by capillary zone electrophoresis following end-column amperometric detection with simplified capillary/electrode alignment

“…The voltammetric characteristics of clozapine have been reported at the wax-impregnated graphite electrode [14], the glassy carbon electrode [15], and the graphite elecElectrophoresis 2000, 21, 1415±1420 Determination of clozapine by CZE 1417 Figure 2.

Electrochemical Behavior and Determination of Clozapine on a Glassy Carbon Electrode Modified by Electrochemical Oxidation

“…The electrochemical behavior of CLZ was well evaluated, and several polarographic and voltammetric methods have been reported for the determination of this drug in literature. [15][16][17][18][19][20] However, some of these methods suffer from sensitivity, and especially reproducibility when a carbon paste electrode is used as the working electrode.…”
