The objective of this study was to improve the overall performance of a glassy carbon electrode (GCE) for the detection of 2,6-diaminotoluene (TDA), a possibly carcinogenic primary aromatic amines (PAAs) that poses a serious risk for the consumer′ health because they can transfer from multilayer food packages including adhesives based on aromatic polyurethane (PU) systems, to the food. The modification of the electrode surface was made by means of multi-walled carbon nanotubes (MWCNTs) and mesoporous carbon nanoparticles (MCNs). The MWCNTs-MCNs/GCE allowed achieving the best performance in terms of sensitivity, as revealed by cyclic voltammetry – CV, with an oxidation peak of 20.95 μA over 0.079 μA of the bare GCE. The pH of the medium influenced the oxidation of 2,6-TDA, with highest sensitivity at pH ∼7. Amperometry experiments led to an estimated detection limit of 0.129 μM, and three linear ranges were obtained for 2,6-TDA: 0.53-11.37 μM, 11.37-229.36 μM, and 229.36-2326.60 μM. Chronoamperometry experiments combined with Cottrell′s theory allowed estimating a diffusion coefficient of 2,6-TDA of 1.34 x 10-4 cm2s-1. The number of electrons (n∼1) involved in the catalytic oxidation of 2,6-TDA was determined according to the Laviron′s theory. Real sample tests demonstrated that the modification of the sensor using nanoparticls allowed to obtain a highly sensitive and selective sensor, which can possibly used as an alternative anal. device for the rapid, easy, and reliable determination of 2,6-TDA. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8SDS of cas: 6683-19-8).
2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.SDS of cas: 6683-19-8
