Electrochemical behavior of a cation-exchange resin modified with copper ions on non-enzymatic glucose determination

Electrochemical determination of carbendazim in juice samples using carbon composite electrode modified with ion‐exchange resin

“…The modified composite electrode was prepared following the method described by Papi et al [31], using a mixture of paraffin (20 % w/w), graphite powder (80 %-X w/ w), and cation-exchange resin powder (X w/w). Next, 400 μL of n-hexane was added to a closed flask, which was then heated at 60 °C for 15 min in an ultrasonic bath.…”

“…Although they can be very useful in preconcentrating different types of analytes, ion-exchange resins have been poorly explored in the preparation of modified electrodes for the determination of organic compounds [29]. The most common electrochemical approaches using ion-exchange resins involve using them on CMEs for the quantification of inorganic species [30] or as a support for catalyst species such as Copper (II) ions, which were used for the electrochemical oxidation of glucose [31].…”
