“…A comparative analysis between the use of more and less components for modified electrodes has not shown significant differences related to stability and sensitivity. On the other hand, some of the most notable advantages of MoO 2 and other metals oxides, that justify the use in the modification of electrodes are; low toxicity, high chemical and thermal stability and a high dielectric constant [24]. Moreover, the currents increase considerably, possibly, electrostatic interactions between the metal ion and the analyte occur with an increase in the surface area [14,25].…”

This report allowed the detection of three substances using a carbon paste decorated with MoO 2 (MoO/CPE). Tartrazine (TZ), sunset yellow (SY) and thiomersal (TMS) were analyzed for adsorptive voltammetry. The electrode was characterized by scanning electron microscopy, energy dispersive spectroscopy and cyclic voltammetry. TZ, SY and TMS were observed at 1.07, 0.80 and 0.95 V respectively. The detection limits (3*σ/m) for TZ, SY and TMS were 0.04, 0.06 and 0.10 μmol/L, respectively. The new analytical method was applied using pharmaceutical samples.

“…Lanthanum (III) oxide has not been used to detect SY-TZ but has been used to detect thimerosal combined only with carbon paste [10]. Combinations with other substances, such as carbon nanotubes and graphene, have been used to detect biological substances [11,12] and pharmacological substances [13][14][15]. These reports are evidence of the great versatility of La 2 O 3 in the modification of electrodes applied to detect different analytes, in this case, dyes.…”

This report describes the simultaneous detection of the two dyes most commonly used in food, tartrazine (TZ) and sunset yellow (SY), based on a microcomposite of carbon paste decorated with La 2 O 3 and TiO 2. Anodic currents for SY-TZ were observed at 0.89-1.21 V by cyclic voltammetry (CV) separated with a ΔV of 0.32 V. The increased anodic peak currents compared to that of the unmodified carbon paste electrode were almost 50 and 41% for SY-TZ, respectively. The detection limits with the optimal amount of Lawere 0.02 and 0.03 µmol/L, respectively. The relative standard deviation (RSD) based on fifty measurements was less than 3%. The versatility and novelty of the sensor were tested with food samples containing these substances and other substances.

The high surface‐to‐volume ratio and desirable chemical, thermal, and catalytic properties of nanomaterials have made them promising electrode materials for sensing applications. As such, different nanomaterials and their nanocomposite‐based individual and/or simultaneous detection of dihydroxybenzene (DHB) have been reported in recent years. Due to the low degradation rate and high toxicity of DHB isomers, the development of innovative and robust sensors for their simultaneous detection has received considerable attention. In this review, applications of different nanomaterials (with the exception of carbon nanotubes, graphene, and their derivatives) for individual and/or simultaneous detection of DHB are briefly discussed. The focal point is on the characteristic features of the modified electrodes that improve their electrocatalytic activities toward DHB. Real sample analysis and electrolyte media are also summarized. This review includes studies published from 2011 to 2020.
