Ascorbic acid determination using a carbon paste electrode modified with iron(III) ions adsorbed on humic acid
An amperometric sensor was constructed, by using humic acids to immobilize Fe3+ ions ona carbon paste electrode (CPE-HA-Fe), and used for ascorbic acid (H2A) determination. The cyclicvoltammogram of the electrode showed electrochemical response due to the Fe3+/Fe2+ couple atE1/2=+0.78 V vs SCE, usin...
