Sensitivity change of the modified carbon paste electrodes for detection of chlorinated phenoxyacetic acids

Carbon paste electrode (CPE) was modiﬁed with F-300 commercial activated carbon or Norit SX-2 powdered activated carbon. CPEs were prepared for detection of 2,4-dichlorophenoxyacetic acid (2,4-D), 2,6-dichlorophenoxyacetic acid (2,6-D) and 2,4,6-trichlorophenoxyacetic acid (2,4,6-T). The electrochemical behavior of these materials was investigated employing cyclic voltammetry (CV) and diﬀerential pulse voltammetry (DPV). The modiﬁer was found to enhance the electroactive surface area and the peak current in comparison to the bare (unmodiﬁed) carbon paste electrode. The intensity of the signal increased with the increase in adsorption ability of the modiﬁers. Compared to the unmodiﬁed electrode, all the new paste electrodes showed a much greater sensitivity for detection of chlorinated phenoxyacetic acids in water samples.

期刊介绍： The content, aim and scope of the proposals should comply with the main subject of the journal, i.e. they should deal with mathematical modelling and/or experimental investigations on momentum, heat and mass transfer, unit processes and operations, integrated processes, biochemical engineering, statics and kinetics of chemical reactions. The experiments and modelling may cover different scales and processes ranging from the molecular phenomena up to production systems. The journal language is grammatically correct British English. Chemical and Process Engineering publishes: i) full text research articles, ii) invited reviews, iii) letters to the editor and iv) short communications, aiming at important new results and/or applications. Each of the publication form is peer-reviewed by at least two independent referees.
