Distribution of microamounts of M2+ during NiSO4 center dot(NH4)2SO(4)center dot 6H(2)O crystallization
Distribution coefficients (D) of trace amounts of Co, Zn, Cu2+, Cd2+, Mn2+, Mg2+, Fe2+, and Ca2+ have been found during crystallization of NiSO4. (NH4)(2)SO4. 6H(2)O at 25 degreesC and 23 degreesC. These values are affected mainly by solubilities of the corresponding double salts. Most of the microcomponent D values could be estimated from solubilities of their double salts. Some of the values are in good agreement with experimental data.
