METHOD FOR CRYSTALLIZING COBALT SULFATE HYDRATE AND COBALT SULFATE HYDRATE OBTAINED USING SAME

摘要

The present invention relates to a method for crystallizing cobalt sulfate hydrate and to cobalt sulfate hydrate obtained using the same, and more specifically, to a method for crystallizing cobalt sulfate hydrate, and to cobalt sulfate hydrate obtained by the method for crystallizing the cobalt sulfate hydrate of the present invention, wherein the method comprises the following steps: mixing an aqueous solution of CoSO_4 with an alcohol in an amount of 0.5 to 3 wt% per 1 wt% of an aqueous solution of CoSO_4 to form a mixture; precipitating the mixture to obtain precipitated cobalt sulfate cobalt hydrate (CoSO_4·xH_2O); and crystallizing the cobalt sulfate hydrate by evaporation under reduced pressure.;COPYRIGHT KIPO 2018
