Bulk Modification of Sonogel–Carbon with Polyaniline: A Suitable Redox Mediator for Chlorophenols Detection

In this work, the development and characterization of a new ceramic material modified with polyaniline powder obtained by high-power ultrasound sol-gel route is presented. A preliminary screening conducting polymer electroactivity was performed means cyclic voltammetry in free analyte solution. Remarkable figures merit for 4-chloro-3-methylphenol (PCMC) determination, selected as model organic analyte, developed material: sensitivity limit detection were 2.40 μA/μM·cm2 0.69 μM, respectively. The device also successfully applied electrochemical determination PCMC water samples collected from different sources, obtaining recovery values ranging 92% to 105%. performance other chlorophenols interest better comparison bare electrode all cases, due presence bulk modifier material. Therefore, can be promoted assays buffer real media environmental monitoring.
