Cathodic Pretreatment of Boron‐Doped Diamond Electrodes and their Use in Electroanalysis

Amperometric flow-injection determination of the anthelmintic drugs ivermectin and levamisole using electrochemically pretreated boron-doped diamond electrodes

“…by a proper electrochemical pretreatment (cathodic or anodic pretreatment, respectively) [29][30][31][32]. As has been previously summarized [32], increased electroanalytical performances have been attained in the determination of additives in food products and drugs in pharmaceutical formulations after the BDD electrode was cathodically pretreated; more recently, this has happened e.g.…”

“…by a proper electrochemical pretreatment (cathodic or anodic pretreatment, respectively) [29][30][31][32]. As has been previously summarized [32], increased electroanalytical performances have been attained in the determination of additives in food products and drugs in pharmaceutical formulations after the BDD electrode was cathodically pretreated; more recently, this has happened e.g. for food colorants [33], and the pharmaceuticals albendazole [34], propylthiouracil [35], bezafibrate [36], hydroxychloroquine [37], hydroquinone [38], diclofenac [39], ciprofloxacin [40], and paracetamol/caffeine/orphenadrine [41] or propanolol/hydrochlorothiazide [42] simultaneously.…”

Differential pulse voltammetric determination of albendazole in pharmaceutical tablets using a cathodically pretreated boron-doped diamond electrode

“…Recently, in our research group, it has been observed that the analytical performance of BDD electrodes greatly depends on their surface termination, i.e. whether they are predominantly hydrogen or oxygen terminated [21]; the predominance of a termination type can be attained by proper electrochemical pretreatments. This effect of surface termination was observed, for instance, in the determination of additives in food products [22][23][24] and of drugs in pharmaceutical formulations [25][26][27][28], when cathodically pretreated (predominantly hydrogen-terminated) BDD electrodes presented better performances.…”

Adsorptive Stripping Voltammetric Determination of Trace Level Ricin in Castor Seeds Using a Boron‐doped Diamond Electrode

“…In the last thirty years, BDD has been widely investigated in electroanalysis, especially for voltammetric determination, preferably using cyclic voltammetry (CV), differential pulse voltammetry (DPV) and/or SWV (direct and stripping modes) for both organic and inorganic substances in real samples in trace levels [11][12][13][14][15]. BDD electrodes are well-faceted, hydrophobic, and have low surface energy, so they are a viable material for the direct oxidation of proteins [16].…”
