Modification of carbon paste electrode with Fe(III)-clinoptilolite nano-particles for simultaneous voltammetric determination of acetaminophen and ascorbic acid

Comparison of CV voltammograms of the raw CPE ('a' and 'b') and the modified Fe(III)-NClino-CPE ('c' and 'd') confirmed good electrocatalytic activity of the modified electrode for voltammetric determination of AC and AA, so the peak currents significantly increased in presence of AA or AC species in solution ('c' and 'd').180
