Simultaneous Electrochemical Determination of Dihydroxybenzene Isomers at 1-Butyl-3-Methylimidazolium Hexafluorophosphate Modified Pencil Graphite Electrode
A simplistic and inexpensive electrochemical platform has been fabricated for the simultaneous detection of Dihydroxybenzene Isomers (DHBIs); named- Hydroquinone (HQ), Catechol (CC) and Resorcinol (RS); in aqueous system. Cyclic Voltammetry (CV) and Differential Pulse Voltammetry (DPV) were adopted for the detection technique. 2B pencil (Faber Castell) collected from the resident stationary shop was used for fabricating Pencil Graphite Electrode (PGE) used as working electrode. PGE was characterized by SEM and EDX. It was modified electrochemically by ionic liquid, 1-Butyl-3-Methylimidazolium hexafluorophosphate (BIHP). Total analyses were performed in phosphate buffer solution (PBS) at pH 7.0. BIHP-PGE showed good selectivity and robust anti-interference for detection of HQ, CC and RS simultaneously in aqueous media. For HQ, CC and RS, the limit of detection is 9.09 μML -1 , 8.15 μM L -1 and 26.78 μM L -1 respectively and sensitivity is 525.21 μA/mM/cm 2 , 585.68 μA/mM/cm 2 and 178.00 μA/mM/cm 2 respectively at BIHP-PGE in simultaneous detection.
