“…Because copper(II) interferes, back-titration technique and a successive approximation approach are used. Hydroxyl groups in polyesters have been determined by esterification with a large excess of CF3COOH and titration of the water thus formed (227). Nitro compounds have been determined by reduction with T1CI3 and titration of the resulting water (187).…”

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).
