“…5c), it can be seen that there are three pairs of redox peaks and a single reductive peak, while the pair of redox peak at about 0.4 V is almost to be disappeared. Voltammetric behavior of the ARS/MWCNT/ GC electrode is in accordance with that of the glass carbon electrode adsorbed with ARS [31]. Moreover, if the ARS is polymerized on the surface of electrode modified with MWCNTs, only the redox peak at about 0.8 V is left while the other peaks are disappeared [32].…”

In this work, an easy and effective method to synthesize alizarin red S/multi-walled carbon nanotube (ARS/MWCNT) nanocomposites based on the p-p stacking non-covalent interactions between ARS and MWCNTs was introduced. The characters of ARS/MWCNT nanocomposites were investigated by Fourier transformation infrared spectroscopy, UV-Vis spectroscopy, X-ray photoelectron spectroscopy, scanning electron microscope, and electrochemical techniques. ARS tightly coating on MWCNTs surface makes the nanocomposites good dispersibility in water and excellent electrochemical activity. Because of the combination of the excellent electroactivity of ARS and the unique properties of MWCNTs, ARS/ MWCNT nanocomposites-modified glassy carbon electrode exhibits a good response to the reduction of hydrogen peroxide and takes on a promising prospect of the practical application in electrochemical sensors field.

“…The cathodic peak potential of adsorbed ARS species showed a near-Nernstian response to changes in pH. The peak separation also changed with pH, giving a maximum at pH 4.0, as reported previously by us [16] and others [30]. The cyclic voltammogram of the copper incorporated ARSGCE electrode in 0.5 M sulfuric acid (pH 0.0) was characterized by a sharp reversible wave centred at -0.15 V and an additional anodic peak at þ0.07 V,…”

“…There was no particular difference in voltammetric responses between the adsorbed ARS species and ARS in solution. Similar electrochemical behavior of anthraquinone derivatives at preanodized glassy carbon electrodes have been reported by us [15][16] and others [8]. The peak currents of the ARS waves were proportional to the scan rates, typical of a surface-bound redox species.…”

“…Gomathi and co-workers [14] reported the enhancement of quinone-hydroquinone adsorption on glassy carbon electrodes after oxidizing treatment in a 1:1 concentrated nitric acid-sulfuric acid mixture. We have recently reported the potentiometric pH sensor utilizing anthraquinonesulfonate adsorbed on preanodized glassy carbon electrodes [15] and also the incorporation of alizarin red S species onto electrochemically activated glassy carbon electrodes [16].…”

Electrochemically activated glassy carbon electrodes adsorbed with alizarin red S (ARS) were applied to the electroanalysis of metal species. Copper species were readily extracted onto the ARS modified electrode and were determined electrochemically. Experimental results showed that the voltammetric peak current resulted from copper incorporation on ARS modified electrodes was significantly larger than that obtained on bare activated electrodes. Voltammetric peak currents showed linear response for copper concentrations in the range between 0.001 and 0.15 mM with a slope of 1.77 A M -1 (correlation coefficient: 0.998). The reproducibility of the voltammetric measurements was found to be within 10 % RSD for five replicate measurements on copper concentration of 0.10 mM. The modified electrodes could be applied for repeated copper determinations without appreciable deterioration in electrode response.

“…In particular, alizarin red S (1,2-dihydroxyanthraquinonesulfonate) has been reported for the complexation of metal ions (Ca, Zr, and Hf ) using the potentiometric [14], voltammetric [15], and spectrophotometric [14±16] methods. In addition, voltammetric behavior of alizarin red S itself adsorbed on the pretreated glassy carbon [17] and the determination of the Cu 2 ion employing adsorptive voltammetry through the complex formation reaction [18] have been studied. However, alizarin (1,2-dihydroxy-9,10-anthraquinone) containing two redox-active quinoid fragments and 9,10-dioxo unit had been applied for the polarographic determination of Al using the complex formation reaction [19].…”

Determination of Ca 2 ions with 4 mL À5.0610 À3 M alizarin and 5 % Na®on-modi®ed electrode was studied employing cyclic voltammetry and chronoamperometry. The Na®on ®lm fabricated in different humidities gave different responses for the Ca 2 ion, of which morphology was characterized with atomic force microscope. Various experimental parameters, which in¯uenced the sensitivity of the modi®ed electrode to Ca 2 ions, were optimized. The modi®ed electrode covering the Na®on ®lm at the low humidity of 40 % was stable in all experiments. The electrodes were stable over pH 4±12 and cation interference could be avoided by controlling the pH of the sample solution. . The correlation coef®cients were 0.997 for both cases. The relative standard deviation was AE 4.7 % at 1.0610 À5 M for ®ve determinations. From the signal-to-background characteristics of the response, the detection limit was about 1.0610 À6 M. Satisfactory results were acquired for the determination of the Ca 2 ion in the certi®ed standard urine reference material (SRM's 2670) and in tap water.
