Abstract
Phenylhydrazine, phenol, and hydroxylamine are three important water pollutants, and the presence of them is harmful for the human body. Therefore, in the present study, 1-methyl-3-butylimidazolium bromide (MBIZBr) and CoFe2O4 nanoparticles (NPs) were successfully used for the amplification of carbon paste electrode (CPE) as a novel voltammetric sensor for phenylhydrazine (PHy) analysis in the water solutions. The CoFe2O4 NPs were characterized by a transmission electron microscopy (TEM) technique. Voltammetric methods were performed to assess the electrochemical act of MBIZBr/CoFe2O4 NPs/CPE towards PHy in aqueous solution. The voltammetric responses reveal the significant enhancement of oxidation current with increased sensitivity. Square-wave voltammetric responses showed three separated oxidation signals for phenylhydrazine, phenol (PL), and hydroxylamine (HX). Using a slope of the calibration curves, limits of detection were calculated to be 7.0 nM, 0.2 μM, and 1.0 μM for PHy, PL, and HX, respectively. The MBIZBr/CoFe2O4 NP/CPE was used for analysis of PHy, PL, and HX in wastewater samples.
