Development of a poly(alizarin red S)/ionic liquid film modified electrode for voltammetric determination of catechol

Abstract

a b s t r a c tA novel modified electrode for voltammetric catechol determination was fabricated by electroploymerization of alizarin red S (ARS) onto a glassy carbon electrode (GCE) in one kind of room-temperature ionic liquid (1-butyl-3-methylimidazolium tetrafluoroborate, BMIMBF 4 ). The polymeric ARS/ionic liquid (PARS/BMIMBF 4 ) film modified electrode was characterized by using scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR) and electrochemical methods. The EDX, XPS and FTIR results indicated that PARS/BMIMBF 4 film was successfully obtained. Compared with the GCE modified by electroploymerization of ARS in aqueous solution, the GCE modified by electroploymerization of ARS in BMIMBF 4 showed smoother and more compact morphology for coating and better electroanalytical properties. Given the combined electrochemical activity of PARS and excellent conductivity of BMIMBF 4 , the PARS/BMIMBF 4 /GCE has been successfully used for catechol determination by differential pulse voltammetry (DPV) with a linear range of 0.10 to 500 M. The sensitivity and detection limit are 42 nA/M and 0.026 M, respectively. The PARS/BMIMBF 4 modified electrode was successfully applied to the determination of catechol in real water samples and may serve as a simple but high-performance sensor for the determination of some environmental pollutants.

Highly Sensitive Square Wave Voltammetric Determination of Sunset Yellow at a Functionalized‐MWCNTs/poly(Alizarin Red‐S) Composite Modified Electrode

“…In this case, the intensity of the peak at 1443 cm À 1 decreased due to formation of the symmetrical S=O group in the structure, and a peak at 1100 cm À 1 belonging to the symmetrical S=O group emerged in this case, it can be said that some of the both asymmetric and symmetric S=O groups may exist in polymer. These observed characteristic peaks are in good agreement with previously published studies [20,29]. In addition, as a result of polymerization, a peak belong to À CÀ OÀ formed in the À COC-À group formed as a result of polymerization at 1043 cm À 1 in both poly(ALR-S)/ GCE and f-MWCNTs/poly(ALR-S)/GCE.…”

“…For example, poly-ALR-S/ MWCNTs/GCEs have been used for the simultaneous determination of and serotonin [20], simultaneous determination of Vitamin K1 and Vitamin D3 [26] and sensitive determination of nitrite ions [27]. ALR-S has not been only electropolymerized on MWCNTs/GCE, but also on different types of electrodes such as GCE [28], ionic liquid/GCE [29], graphene/GCE [30], pyrolytic graphite electrode [31] and pencil graphite electrode (PGE) [32,33], and these electrodes have been utilized for the electrocatalytic oxidation and voltammetric determination of different analytes. However, our literature search shows that poly-ALR-S/MWCNTs/GCE has not been used for the voltammetric determination of SSY.…”

Non-Enzymatic Selective Determination of Catechol Using Copper Microparticles Modified Polypyrrole Coated Glassy Carbon Electrodes

“…In contrast to hitherto-known non-enzymatic methods available for sensing of CC, 17,25,26,[71][72][73][74][75] we have demonstrated here, a nonnoble metal based electrode with impressive sensing characteristics. It is also important to mention here that the modified electrode displays a wide linear range and a low limit of detection in comparison with other PPy modified electrodes available for detection of CC.…”
