“…10 inset B). In comparison with previous reports (Alemu et al, 2002 and2003;Ghalkhani et al, 2010;Mehretie et al, 2012;Wang et al, 2014;Dede et al, 2014), the prepared sensor has higher sensitivity and lower limit of detection (Table 1), which mainly ascribe to the large surface area and strong adsorption of both Pal and Gr-COOH, including high surface catalytic activity of Gr-COOH.…”

“…NA is usually unstable in strong acid medium (Mehretie et al, 2012), while it is easily hydrolyzed in strong alkaline media (Al-Hadiya et al, 2005), thus the effect of pH values on the NA determination at Pal-Gr-COOH/GCE over the range of pH 4.0 -8.0 was explored by DPASV. The peak currents of NA at Pal-Gr-COOH/GCE increased gradually with the increasing pH value until it reached the maximum at pH 7.0, but it decreased rapidly when pH increased further (Fig.…”

“…Ghalkhani et al fabricated carbon nanoparticle/chitosan nanocomposite modified electrode for detecting NA, and it showed high stability, good reproducibility and excellent electro-catalytic activity toward NA (Ghalkhaniet al, 2010). Mehretie et al also investigated poly (3,4-ethylenedioxythiophene) modified glassy carbon electrode (GCE) towards the electrochemical determination of NA with excellent performance (Mehretie et al, 2012). In our previous work, we also built electrochemical sensors based on carbon nanomaterials modified GCE with wonderful properties .…”

The stably dispersible palygorskite (Pal) nanorods onto carboxyl functionalized graphene (Gr-COOH) nanosheets were successfully employed for the facile fabrication of a novel nanohybrid sensing platform and the voltammertric determination of niclosamide (NA) in tablet and paddy water samples. A water-processable Gr-COOH can improve the dispersion and stability in water of Pal. The structure and properties of the formed Pal-Gr-COOH nanohybrid were characterized. The electrochemical behavior of NA, analytical conditions and the sensing performance of the prepared sensor were investigated. The sensor displayed the enhanced synergistically electrocatalytic ability toward NA in a linear range from 0.02-0.99 M with low limit of detection (4.6 nM), good sensitivity, high reproducibility and satisfactory practicability, suggesting Pal-Gr-COOH nanohybrid will provide a promising platform for sensing application and facile preparation and potential application of other nanoclay mineral nanocomposites.

“…Poly (3,4-ethylenedioxythiophene), PEDOT, which is a relatively new and well-known conjugated polymer, has received relatively high attention because of its high electrical conductivity and excellent environmental stability. Thus, PEDOT has emerged as one of the most stable and promising electrode materials offering the possibility modification with different chemical groups for the determination of phenols, dopamine and ascorbic acid [24], paracetamol [25], N-acetylp-aminophenol and p-aminophenol [26], and niclosamide [27].…”

Phenol and chlorophenols were investigated using single-wall carbon nanotubes (SWCNT) and poly(3,4-ethylenedioxythiophene) (PEDOT) composite modified glassy carbon electrode (SWCNT/PEDOT/GCE) as a detector in flow injection system. Optimization of experimental variables such as the detection potential, flow rate, and pH of the carrier solution (0.1 M sodium acetate) for the determination of phenol (P), 4-chlorophenol (CP), 2,4-dichlorophenol (DCP), 2,4,6-trichlorophenol (TCP), and pentachlorophenol (PCP) were performed. Under these conditions, analytical parameters were calculated from the calibration curve of measured amperometric responses as a function of concentrations of phenol and chlorophenols. The designed electrode exhibited very good analytical performance. The designed electrode was tested with 20 repetitive injections of each analyte and showed good operational stability. The analytical performance of the SWCNT/PEDOT/GCE electrode under flow through conditions was tested and was found to be impressive. The electrode showed a wider dynamic range for the detection of phenol and chlorophenols with low limits of detection compared with other enzymatic and nonenzymatic sensors. These results suggest that the method is quite useful for the analysis and monitoring of phenols and chlorophenols.
