Determination of Milligram Quantities of Vandium in Presence of Uranium

Abstract

An improved method for the determination of milligram quantities of vanadium in the presence of uranium is described. Use of a modified dead-stop procedure and a weight microburet increases the sensitivity and precision of the method.Results are given in the range of 0.10 to 4.0 mg. of vanadium.

Potentiometric Titrations

“…Chlorite ion may be titrated accurately in slightly alkaline solution with standard ferrous sulfate solution, according to Weiner (87). Gale and Mosher (20) applied the dead-stop end-point technique to the determination of milligram quantities of vanadate in uranyl solutions.…”

Argentometric Determination of Halides Using Dead-Stop End Point

“…point (3,4,7,13). A second type is to be found where the same substance undergoes both oxidation at the anode and reduction at the cathode (6,11).…”
