What is A Glassy Carbon Supported Bilayer Lipid-like Membrane of 5,5-Ditetradecyl-2-(2-trimethyl-ammonioethyl)-1,3-dioxane Bromide for Electrochemical Sensing of Epinephrine about?
A self-assembled bilayer lipid-like membrane (BLM) supported on glassy carbon electrode (GCE) was fabricated using 5,5-ditetradecyl-2-(2-trimethyl-ammonioethyl)-1,3-dioxane bromide (DTDB) for epinephrine (EP) determination in the presence of ascorbic acid (AA). This modified electrode (DTDB/GCE) has strong membrane adsorption accumulation and electrocatalytic ability toward EP and AA. The oxidation of EP was controlled by double step adsorption accumulation process of the DTDB-BLM. The parameters of fitted Langmuir isotherm Γ max , B ADS , and G ADS values were determined as 1.0 × 10 -11 mol cm -2 , 2.04 × 10 6 dm 3 mol -1 , and -45.17 kJ mol -1 for the fist step for EP concentration less than 1 mM, and 4.92 × 10 -11 mol cm -2 , 7.35 × 10 4 dm 3 mol -1 , and -37.1 kJ mol -1 for the second step for EP concentration higher than 1 M. The DPV peaks for EP and AA oxidations were appeared at 0.220 and 0.085 V versus SCE, respectively, allowing the determination of EP in the presence of high concentration of AA. The advantage of DTDB-BLM was demonstrated experimentally in comparison with other three BLMs, and attributed to the dioxane group as well as the suitable length of the carbon cha
