Abstract:

Modified film electrodes represent novel and useful analytical devices capable to offer a fast and reliable response, with improve selectivity and sensitivity over other electroanalytical techniques. The detection of oxalic acid and its oxalate is of interest in biomedical analysis but also in food, paper and drug analysis. Two electroanalytical methods are presented for the detection of oxalic acid, cyclic voltammetry and potentiometric titration using Hg film electrodes
