PAN-incorporated Nafion-modified spectroscopic graphite electrodes for voltammetric stripping determination of lead

Suppression of Protein Adsorption at Glassy Carbon Electrodes Covalently Modified with Tetraethylene Glycol Diamine

“…Four DPV scans were recorded from 0 to 0.55 V, with solution stirring (30 s) between scans and the peak height of the fourth scan was measured and used for analysis. DPV parameters were: scan rate 2 mVs À1 , pulse modulation amplitude 25mV and drop time 0.5 s. 4 . The broad and irreversible oxidation peak appears at a similar potential to those reported for other primary amines [19,20] and hence is assigned to oxidation of the amine functionalities.…”

Differential Pulse Anodic Stripping Voltammetric Determination of Traces of Copper with a Tobramycin-Nafion Modified Electrode

“…Incorporation of some complexing reagents can improve the sensitivity and selectivity of polymermodified electrodes. [27][28][29][30] In this work, the function of Nafion was not only to fix tobramycin on the glassy carbon electrode surface, but also to serve as a barrier to prevent interferents from reaching the electrode surface where the electrochemical process takes place. The present study has led to the development of a voltammetric method for the determination of Cu…”

Nafion-Coated Mercury Film Electrodes for Square Wave Stripping Voltammetry Determination of Lead and Cadmium in Continuous Flow

“…Although it has been reported [10,34] that the anodic stripping determination of lead at Nafion coated electrodes is rather problematic in the presence of Triton X-100, it should be emphasized that in the experimental conditions presented here the interference can be largely mmimized through the use of the NCMFE. The obtained results basically agree with data found previously by other authors at mercury film electrodes modified with cellulose acetate [16] and Nafion [13,[31][32][33].…”
