- Determination of hydroquinone in a square wave voltammetry procedure using a graphite-polyurethane composite electrode P. Cervini E.T.G. Cavalheiro Química polyurethane composite electrodes square wave voltammetry In order to a better characterization of a graphite-polyurethane composite intended to beused as a voltammetric sensor, the performance in a square wave voltammetric procedure was investigated.Using hydroquinone (HQ) as a probe, the electrode showed to be useful in square wave voltammetrywith limit of detection of 0.28 µmol L-1, with recoveries between 99.1 and 101.5%. The resultsof the proposed method agreed with HPLC ones within 95% confidence level. 2006 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42931409 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Num.4 Vol.31
