Oxidation states higher than + 3 are exhibited by Ce, Pr, and Tb, but only Ce4+ is stable (kinetically) in water. It is a very strong oxidizing agent in aqueous solution ( ° = 1.74 V) and is used as a volumetric standard in redox titrations. Some of its salts [e.g., cerium(IV) ammonium nitrate, cerium(IV) sulfate] find application in... [Pg.840]

Cerium (TV) ammonium nitrate (CAN)37 and a cerium (TV) impregnated resin38 are able to catalyze the selective oxidation of secondary alcohols with sodium bromate (NaBrOi). Stoichiometric cerium bromate— CelBrCb h, prepared in situ from barium bromate and cerium (III) sulfate, is also able to perform selective oxidations of secondary alcohols.39... [Pg.346]

Ciprofloxacin was determined in tablets and intravenous infusion solutions by an oxidative spectrophotometric method [15]. A yellow-orange complex was obtained upon reaction of ciprofloxacin with 5% ammonium sulfamate, 5 N H2S04, and 0.1 M cerium(IV) ammonium sulfate. The complex was extracted into CHC13, dried with anhydrous Na2S04, and measured at 345 nm within up to 4 h. Beer s law was obeyed over the range of 12-120 pg/mL, and the molar absorptivity was found to be 5090. [Pg.191]

Ammonium cerium(IV) nitrate or cerium(IV) sulfate will catalyze the selective oxidation of secondaiy alcohols with sodium bromate as cooxidant, in this case remote C—C double bonds interfere, but 1,2-diols are not cleaved. It has been found that sodium bromite in aqueous acetic acid will act as a selective oxidant for secondary mary diols without the need for other catalysts (Scheme 21). ... [Pg.322]

Ammonium cerium sulfate (ceric ammonium sulfate), (NH4)2Ce-(804)4 2(NH4)2S04 2H20, converts aromatic polynuclear hydrocarbons into quinones [429]. [Pg.17]

Cerium(IV) presents an interesting case. The useful oxidant ceric ammonium nitrate (CAN) can be extracted from an aqueous solution as a complex salt [NBu4]2[Ce(N03)6] into hexane. Ceric ammonium sulfate, however, being a true double salt, cannot be transferred by a QX catalyst [14], In an actual catalytic oxidation procedure, naphthalene is converted into naphthoquinone in a water/hexane... [Pg.274]

A number of transition metals can be determined conveniently if their cations undergo a definite change of oxidation state see Oxidation Number) on titration with a standard solution of potassium permanganate, potassium dichromate, cerium(IV) sulfate, or ammonium hexanitratocerate(IV). Several visual indicators have been proposed, including diphenylamine and its derivatives, xylene cyanole FF, and especially A-phenylanthranilic acid and tris(l,10-phenanthroline)iron(II) sulfate ( ferroin ). Solutions of have been used in the determination of iron, copper, titanium, vanadium, molybdenum, tungsten, mercury, gold, silver, and bismuth, and standard solutions of and Sn F U, and and Mo have also... [Pg.202]
