In situ surface electrochemical co-reduction route towards controllable construction of AuNPs/ERGO electrochemical sensing platform for simultaneous determination of BHA and TBHQ

Metal organic framework (ZIF-67)-derived Co nanoparticles/N-doped carbon nanotubes composites for electrochemical detecting of tert-butyl hydroquinone

“…The phenolic antioxidants play a significant role in preventing the decomposition of organic compounds in the food and pharmaceutical industries [1]. As one of the synthetic phenolic antioxidants (SPAs), tert-butyl hydroquinone (TBHQ) is widely used in edible oils and meat products, ascribed to its antioxidant ability, low cost and stability [2,3]. But the excessive use of TBHQ is responsible for vision disturbance, convulsions and medullary dysfunction as reported by the national institute of health [4].…”

Development of a photoelectrochemical sensor for detection of TBHQ antioxidant based on LiTCNE-TiO2 composite under visible LED light

“…A detection limit (LD) of 100 nmol L −1 was determined using the equation LD = 3 σ bl / slope, where σ bl is the standard deviation of the blank response which is obtained from 10 replicate measurements of the blank solution and slope is the slope of the analytical curve. The linear range of response and limit of detection were analyzed in comparison to electrochemical sensors to TBHQ reported in the literature (Table 1) [37][38][39][40][41][42][43][44]. As can be seen, the LiTCNE/TiO 2 photoelectrochemical sensor shows a linear range of response about of three magnitude orders and a limit of detection of 100 nmol L − 1 , which is comparable to the best electrochemical sensors to TBHQ.…”

Gold Nanomaterials-Based Electrochemical Sensors and Biosensors for Phenolic Antioxidants Detection: Recent Advances

“…Different examples of multianalyte detection have been introduced in this review, involving phenolic acids, flavonoids, and synthetic phenolic antioxidants [ 74 , 146 , 184 , 187 , 189 ].…”

“…Wang and coworkers developed an electrochemical sensor for the simultaneous detection of BHA and TBHQ in edible oils, using GCE modified with a binary nanocomposite including AuNPs and ErGO [ 187 ]. The nanocomposite was electrochemically prepared by the co-reduction of GO and the AuNPs precursor onto the GCE surface.…”

“…This sensor was assembled via electropolymerization using o -phenylenediamine as functional monomer in the presence of PG as template molecule on the surface of GCE modified by the PtAu-rG-CNTs nanohybrid. The nanohybrid was prepared via co-reduction of PtAuNPs precursors and GO, in the presence of CNTs, according to the procedure reported previously in the literature [ 187 ]. Using thee PtAu-rG-CNTs composite as the electrode material can improve the electrochemical sensor performances, increasing the active surface area and the electron transfer rate, while MIP acted as a key recognition element, as already reported.…”
