- W2381532893 abstract "A novel composite film modified electrode [GdL3(HL)]·H2O(HL=1-(p-methylphenyl)-3-methyl-4-(α-furoyl)-5- pyrazolone/ poly-2,2-bipyridyl(Pbpy)/ glassy carbon electrode(GCE)was prepared for the determination of 2,6-di-tertbutyl-4-methylphenol(BHT)which was a food additive. The cyclic voltammetry(CV) and differential pulse voltammetry(DPV) were used to characterize the electrochemical behavior and to study the reaction mechanism of BHT on the electrode. Compared with the bare GCE and Pbpy/GCE, the [GdL3(HL)]·H2O/ Pbpy/GCE showed an excellent electro-catalytical effect on the oxidation of BHT with a significant increase of the peak current. When the pH was 5.0, an oxidation peak with Ep=0.212V was produced on the new modified electrode. The difference of peak potentials(△Ep) was 400mV lower than on bare GCE, and about 42mV lower than on Pbpy/GCE electrode. Meanwhile, the peak current markedly increased. Under the optimum conditions, the oxidation peak and BHT showed a good linear relation when the BHT concentration range was 6.0×10-6~2.0×10-4mol·L-1. The detection limit was 1×10-8mol/L." @default.
