This paper describes a novel electrode material, diclofenac-impregnated mesoporous carbon modified with cationic surfactant, cetyltrimethylammonium bromide (DF-CMK-3/CTAB), for ultratrace analysis of the arsenic drug roxarsone (ROX). DF-CMK-3 amorphous is material high specific surface area and well-defined, hexagonally ordered, thin mesopores. The functional groups attached to carbonaceous surface, such as chromene pyron-like oxygen groups, lactam, aromatic rings, have basic character they can donate electrons. Modification CTAB layer significantly increases analytical signal due electrostatic interactions between surfactant anion form ROX in acidic medium. voltammetric procedure at glassy sensor DF-CMK-3/CTAB exhibited excellent sensitivity (limit detection 9.6 × 10−11 M) wide range linearity from 5.0 10−10 1.0 10−4 M. Analysis real samples (treated municipal wastewater river water) showed recoveries 96 102% without applying complicated sample pretreatment step. demonstrated presence interferences environmental water samples.
