“…Extracts have been analyzed using a diverse set of analytical techniques (Table 3), including atomic absorption spectroscopy (AAS) (Frahm et al, 1975;Liebhardt, 1976;George et al, 1982;Nachman et al, 2008), hydride generation with atomic fluorescence spectrometry (HG-AFS) (Wang et al, 2006), gas chromatography with mass spectrometry (GC-MS) (Roerdink and Aldstadt, 2004), and high performance liquid chromatography (HPLC) coupled to UV detectors (Sapp and Davidson, 1993;Croteau et al, 1994;Chen et al, 2011;Chen and Huang, 2012), inductively coupled plasma mass spectrometry (ICP-MS) (Dean et al, 1994;Pergantis et al, 1995Pergantis et al, , 1997aJackson and Bertsch, 2001;Wang et al, 2010), or electrospray ionization mass spectrometry (ESI-MS) (Pergantis et al, 1997b;Wang et al, 2011), among others (Morrison, 1968;George and Morrison, 1971;Ahamad et al, 2000;Yao et al, 2013b).…”

“…Advanced methods developed after 1990 use liquid chromatography coupled to various detectors that allow for low limits of detection: 260 μg/L for roxarsone-selective electrodes (Ahamad et al, 2000), 0.05-25 μg/L for ICP-MS (Dean et al, 1994;Jackson and Bertsch, 2001), and 0.15 μg/L for ESI-MS (Pergantis et al, 1997b). HPLC-ICP- MS methods have been employed due to low detection limits in complex sample matrices (Ogra, 2012); however, these methods are of limited use when unknown, or unidentified, arsenic-containing species are present in solution.…”

“…The limits of detection (LOD) and quantification (LOQ) calculated as LOD = 3SD a /b and LOQ = 10SD a /b [43] were 9.6 × 10 −11 and 3.2 × 10 −10 M, respectively. Table 3 compares the analytical parameters of the developed procedure with those previously described in the literature for other voltammetric sensors [10][11][12][13][14][15][16][17][18][19][20][21][22][23]. As can be seen, we obtained a very wide range of linearity of the calibration curve and additionally the lowest limit of detection in comparison to those that had been described in the literature thus far.…”

Diclofenac-Impregnated Mesoporous Carbon-Based Electrode Material for the Analysis of the Arsenic Drug Roxarsone

et al. 2023

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

Characterization and Use of Copper Solid Amalgam Electrode for Electroanalytical Determination of Triazines-Based Herbicides

et al. 2006

This paper reports the construction, characterization and use of copper solid amalgam electrode in the study of the electrochemical behavior of atrazine and ametryne herbicides by square-wave voltammetry. This study was used as basis for the development of sensitive analytical methods for the determination of these herbicides in natural water, avoiding the use of mercury, by means of a solid electrode that presents high sensitivity and minimizes any environment contamination with mercury residues. The experimental and voltammetric conditions were evaluated and the results showed a reduction peak for atrazine at À 0.98 and at À 1.1 V vs. Ag/AgCl 3.0 mol L À1 for ametryne, both with characteristic of an irreversible electrode reaction in an electrochemical diffusion controlled process, involving two electrons for each herbicide reduction. Based on voltammetric studies, it has been demonstrated that the most possible mechanism for the reduction of herbicides involved reduction of bond carbon-chloride for atrazine and the reduction of bond carbon -SCH 3 for ametryne. The detection limit of herbicides obtained in pure water (laboratory samples) was shown to be lower than the maximum limit of residue established for natural water by the Brazilian Environmental Agency, demonstrating that this methodology is very suitable for determining any contamination by atrazine and ametryne residues in different samples, proving a good substitute for mercury electrodes.
