Preparation and Characterization of Novel Hybrid Nanomaterial Catalyst MCM-41@AzaCrown-SB-cu and its Application in Synthesis of Hexahydroquinoline Derivatives under Solvent-Free Conditions (original) (raw)

The development of new and robust sensors for real-time monitoring of environmental pollutants have received much attention. Therefore, in the present work, we have fabricated a simple and robust electrochemical sensor for the simultaneous electrochemical determination of dihydroxybenzene isomers using chitin (CHI) stabilized graphite (GR) hydrogel composite modified electrode. The GR-CHI hydrogel composite was prepared by a simple sonication of raw GR in CHI solution and the as-prepared materials were characterized by range of physicochemical methods. Compared with CHI and GR modified electrodes, the GR-CHI hydrogel composite modified electrode shows an excellent electron transfer ability and enhanced electrocatalytic activity towards hydroquinone (HQ), catechol (CC) and resorcinol (RC). Differential pulse voltammetry was used for the simultaneous determination of HQ, CC and RC. Under optimized conditions, the fabricated electrode detects the HQ, CC and RC in the linear response from 0.2 to 110.6 μM, 0.3 to 110.6 μM and 1.3 to 133.4 μM, respectively. The detection limit for HQ, CC and RC were 0.065 μM, 0.085 μM and 0.35 μM, respectively. The sensor shows its appropriate practicality towards the determination of HQ, CC and RC in different water samples.
