Volatilization of Iodine from Dilute Iodine-Potassium Iodide Solutions

Abstract

Cobalt and nickel may be determined in the same solution by precipitating them as the complex salts as outlined above, determining the nickel by the dimethylglyoxime method and calculating the cobalt by difference. The reliability of the method was tested by mixing standard solutions of cobalt and nickel sulfates to make two solutions, then analyzing for both by the volumetric method and determining nickel by the dimethylglyoxime method and calculating cobalt by the difference. The results are given in Table III.An examination of the tables shows that this method gives excellent results for cobalt and nickel separately, and that results in the presence of each other compare reasonably well with accepted methods. The method is very rapid and requires no expensive apparatus, as does the method of Spacu for nickel.

“…However, several authors (Hough and Ficklen, 1934;Nowaczyk et al, 1993;Lin, 1981;Ling, 1997) indicated that iodine can be lost by volatilisation. Such loss of iodine to the environment can partially explain the reduction of triiodide concentration, when it is not consumed by gangue minerals.…”
