Preparation of nickel chloride of high purity

Abstract

A method is described for th e preparation of cobalt-free nickel chloride, which consists in th e repeated precipitation by hydrogen chloride of nickel chloride dihydrate from a mixture of a saturated aqueous solu tion of nickel chloride with acetone. Methods are also given for determining cobalt, a luminum, iron, copper, and combined phosphorus and silicon in nickel salts.
