INTAKE OF COPPER PARTICLES IN POLY(o-PHENYLENEDIAMINE-co-p-BENZOQUINONE) DEPOSITED ONTO PLATINUM ELECTRODE: RESPONSE TO gamma-AMINOBUTIRIC ACID

Modified electrodes with o-phenylenediamine and p-benzoquinone copolymer were prepared optimizing the conditions to obtain a polymeric film with an adequate intake of copper. Various electrode materials were assayed, and the copolymer deposit was potentiodynamically prepared on a platinum electrode....
