Abstract
The sol-gel molecularly imprinted films modified glassy carbon electrode was prepared by electrodeposition of tetramethoxysilane(TMOS) and phenyltrimethoxysilane(PTMOS) with chronoamperometry in the presence of template molecules 3,4-dihydroxybenzoic acid(3,4-DHBA) followed by extraction with ethanol.The modified electrode could successfully avoid the polymerization of oxidized 3,4-DHBA and the interference of 2,4-DHBA.A linear concentration response curve was obtained from 1.0 × 10-5 mol·L-1 to 8.0×10-4 mol·L-1,with the detected concentration limit of 5.0 × 10-6 mol·L-1.
