Popis:	The reduction conditions for the accurate determination of small amounts of cerium, chromium, and vanadium were studied. On the basis of the results obtained, the determination of these elements, in the presence of permanganate ions, by a single potentiometric titration with a standard hydroquinone solution was investigated. (tr-auth) l6818 A method for the simultaneous polarographic determination of copper and iron in nickel or aluminum and their salts is presented. The electrolyte used is 0.8 M ethylenediamine tartrate and 0.08 M sodium pyrophosphite. The method is applicable to the analysis of
