A novel electrochem. sensor for rutin determination based on molecularly imprinted poly (ionic liquid) (MIPIL)/ionic liquid-graphene (IL-GR) modified electrode was developed. MIPIL was synthesized via free radical polymerization using rutin as the template, 1-allyl-3-Et imidazolium bromide ([AEIm]Br) as the functional monomer and 1,4-butanediyl-3,3′-bis-L-vinylimidazolium dibromide ([V2C4(mim)2]Br2) as the crosslinker. The composite of IL-GR as an electrode sensitive element was prepared using carboxymethyl-3-methylimidazolium chloride ([HO2CMMIm]Cl) by one-step ultrasound method. Fourier transform IR spectroscopy and scanning electron microscope were used to characterize IL-GR and MIPIL. The increased surface area and conductivity of IL-GR/GCE improved the sensitivity of rutin sensor. Under the optimum condition, good linearity for rutin anal. by the MIPIL-based sensor was obtained from 0.03 to 1μM. A low limit of detection for rutin was 0.01μM (S/N = 3). The MIPIL-based sensor demonstrated superiority on DPV response compared to the imprinted sensors based on traditional crosslinkers. The proposed sensor presented good selectivity for rutin and successfully applied for rutin determination in tablets with RSD of 3.05% and the average recovery range was 98.3%.
