“…A number of electrochemical techniques based on the oxidation of ascorbic acid have been developed for analysis of the vitamin [43][44][45][46][47][48]. Pradac and Koryta [49] have used a platinum electrode to measure the concentration of L-ascorbic acid in the cortex of an isolated kidney.…”

“…Ethylene glycol in mixtures with diethylene glycol has been determined by selective oxidation with NaI04, addition of arsenite, and coulometric titration with externallygenerated iodine to a starch end point (248). An automated coulometric assay system for ascorbic acid and sodium ascorbate employs bipotentiometric indication (259). Coulometric potentiometric titration with iodine has been used along with the analogous titration with bromine to analyze mixtures of cysteine and ascorbic acid (204).…”

The period covered by this survey is from the previous reviews (82, 342,343) through October, 1975. Unless otherwise specified, potentials are with respect to the saturated calomel electrode (SCE). In each area, the intended order of treatment is amperometric, bipotentiometric, and nonamperometric or coulometric. Many coulometric titrations are monitored amperometrically. When thus identified, they have been treated as amperometric titrations.Reviews of amperometric titrimetry include general aspects (326, 335), continuous analysis (185), nonaqueous systems (382), trace determinations (336), inorganic microanalysis (309), determination of antibiotics (364), measurements for industrial uses (253), determination of niobium (234), uses of 8-mercaptoquinoline (28), and of organic reagents in general (265). The value of polarized electrode titrimetry has been discussed (201). In addition to general aspects (31, 67, 142), reviews of coulometric titrimetry concern the electrogeneration of reagents (94), the titration of organic compounds (205), and continuous analysis (186,344,350).
