Data from C.C. Xiao et al Provide New Insights into Phenols [Electrophoretic Separation of Chlorophenols on Silica Nanospheres-coated Poly(dimethylsiloxane) Microchip Using a Nafion/graphene-modified Carbon Electrode for Detection]

By a News Reporter-Staff News Editor at Nanotechnology Business Journal -- Investigators publish new report on Phenols. According to news reporting from Suzhou, People's Republic of China, by VerticalNews journalists, research stated, "In the present work, the micellar electrophoretic separation of five chlorophenols (CPs) on a functionalized poly(dimethylsiloxane) (PDMS) microchip with amperometric detection was performed. In order to achieve high resolution by controlling the electroosmotic flow (EOF) as well as signal detection by suppressing analytes adsorption, the microchannel was functionalized by poly(diallyldimethylammonium chloride) (PDDA)/SiO2 nanospheres (NSs)/poly(sodium-p-styrenesulfonate) (PSS), via an approach of layer-by-layer assembly."

The news correspondents obtained a quote from the research, "Five chlorophenols (2-chlorophenol, 4-chlorophenol, 2,4-dichlorophenol, 2,3-dichlorophenol and 2,4,6-trichlorophenol) were efficiently separated in this microchannel (3.7 cm of length) within 120 s. A resolution of at least 2.4 was obtained with a 10 mM phosphate buffer solution (PBS) (pH 9.48) containing 20 mM sodium dodecyl sulfate (SDS) and 50% (v/v) acetonitrile as a carrier under optimized conditions. A graphene-modified carbon microdisk electrode was used for high-sensitivity detection. Its characteristics were investigated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). For those CPs, linear ranges of 0.08 - 5, 0.06 - 5, 0.04 - 5, 0.04 - 5 and 0.30 - 20 mu M and detection limits of 0.021, 0.026, 0.022, 0.019 and 0.054 mu M were obtained, respectively."

According to the news reporters, the research concluded: "The method was successfully applied for the analysis of some wastewater samples with satisfactory recovery."
