FIELD: chemistry.
SUBSTANCE: invention relates to improved method of obtaining nickel (II) oxalate NiC2O4·2H2O, which includes preparing of reaction water solution, which contains nickel (II), precipitation of nickel oxalate, separating of sediment from solution and its drying, in which as nickel source used are solutions of nickel chloride, nitrate, sulphate, and as reagent-precipator used is anionite AB-17-8 in oxalate form. Obtained product can be applied in industry for producing catalysts, metal films, polymetal alloys, ceramic-metal and ferromagnetic substances, as well as in production of electrovacuum devices.
EFFECT: obtaining target product of high degree of purity, which does not contain admixture anions and cations, which eliminates necessity of long washing of obtained sediment.
