“…Svorc et al performed electrochemical determination of atrazine using boron-doped diamond electrode and square wave voltammetry as technique. 72 Atrazine was electroreduced at À1.1 V vs. Ag/AgCl in Britton-Robinson buffer solution at pH 3.0 as supporting electrolyte. In both cases the detection potential is much higher than in our results, while the range of concentration is similar.…”

2014Poly(dimethylsiloxane) as a pre-coating in layer-by-layer films containing phosphotungstate nanoclusters electrochemically sensitive toward s-triazines RSC Advances,Cambridge : Royal Society of Chemistry -RSC,v. 4, n. 56, p. 29612-29621, 2014 http://www.producao.usp.br/handle/BDPI/50444 One of the major advantages of the Layer-by-Layer (LbL) deposition technique is the possible control of molecular architecture, not only to achieve optimized properties but also to seek synergy among different materials. In this study, LbL films containing nanoclusters of a Keggin type polyoxometalate, phosphotungstic acid (HPW), alternated with the polycation poly(allylamine hydrochloride) (PAH) were deposited on indium-tin oxide (ITO) substrates. The electrochemical properties of the hybrid LbL film investigated in acidic conditions indicated no significant desorption of HPW, when a layer of poly(dimethylsiloxane) terminated with 3-aminopropyl groups (PDMS) was previously deposited on the ITO substrate. Such effect occurred because PDMS prevents desorption of HPW from the hybrid film, asshown by X-ray Photoelectron Spectroscopy (XPS) analyses. The porous structures of the films were revealed by Fourier transform infrared reflection absorption spectroscopy, scanning electron microscopy and XPS. PDMS/PAH as a pre-coating allowed the HPW/PAH films to be sensitive to the electrochemical detection of the triazines atrazine and melamine. In conclusion, the precise control of the LbL films architecture is important to develop opportunities for new applications.

“…30 In order to choose the optimal supporting electrolyte for the chronopotentiometric determination of riboflavin, the effects of various supporting electrolytes were investigated. For this purpose, HCl, HNO 3 , H 2 SO 4 , NaCl, KCl, and Na 2 CO 3 in concentration of 0.01 mol/L and 0.025 mol/L were studied.…”

A novel, simple, sensitive and reliable electrochemical method for the riboflavin determination using chronopotentiometry with glassy carbon electrode was developed. The most important instrumental parameters of chronopotentiometry including type and concentration of supporting electrolyte, initial potential and current range were examined and optimised in respect to riboflavin analytical signal. Riboflavin provided well defined reduction signal at -0.12 V vs. Ag/AgCl (3.5 mol/L KCl) electrode in 0.025 mol/L HCl. Under optimal conditions, linear response of riboflavin was observed in the concentration range of 0.2-70 mg/L with achieved limit of detection of 0.076 mg/L and limit of quantitation of 0.23 mg/L of riboflavin. Common vitamins and excipients did not interfere with the determination. The proposed method was successfully applied for determination of riboflavin in commercially available pharmaceutical preparations. The obtained results were in statistical agreement to the contents declared by manufacturer and to those obtained by HPLC used as a comparative method.

“…It was very attractive to use this material in electroanalysis. Several hundreds of reviews [26], [27] and [28] were published on applications of these electrodes in cyclic voltammetry for the analysis of pesticides, herbicides, pharmaceutical products [29], [30] and [31]. The conductive diamond was also used to manufacture electrodes for electrochemical detection in HPLC and flow injection [32], [33], [34], [35], [36], [37] and [38] electrochemical reactions [39].…”
