Title: Quick determination of phenanthrene in coloured latexes using graphene-modified glassy carbon
Abstract: A facile detection system was devised by attaching graphene to glassy carbon, and the electrooxidation of phenanthrene (Phe) was investigated. The linear sweep voltammetry revealed that the modified liquid quantity and electrolyte concentration affected the oxidation of Phe-acetonitrile-NaClO4 whose applicability conditions were optimised. The peak oxidation current in the range of 1-120 nmol L-1 has a good linear relationship with Phe concentration (I = 0.1066cpHe +19.04, R2=0.9975). Furthermore, we reported an electrochemical assay for Phe in coloured latexeson a graphene-modified glassy carbon. It was meaningful for quick determination of Phe, especially in simpleness and detection time compared with GC–MS.
