Abstract

It has been compared the spectrophotometrical determina­tion of nickel with dimetilglyoxime in samples of two geologically representative profiles of Pinares de Mayarí. Two methods were studied: the dissolution of the sample with aqua regia and further determina­tion of nickel and the dissolution of the sample with hydrochloric acid and the separation of nickel with an anionic resin previous to its analytical determination. The statistical results show us that the second method results to be much preciser and that the first presents a syste­matic error by excess due to the presence of iron in the sample. The complete proposed method is reported as well as the exact contents of nickel in the geological samples.
