Abstract

Solubilities of the quaternary system Li+, K+, Mg2+/SO42--H2O were investigated by isothermal method at 25癈. Physico-chem. properties of solns., such as d., refractive index, viscosity, conductivity, and pH, were determine Phase diagram of the title system consists of six solubility branches and five crystallization fields corresponding to arcanite, lithium sulfate monohydrate, epsomite, picromerite, and double salt (Li2SO4譑2SO4). Pitzer model of electrolyte solution was used for parameterization from results of solubility determination for subsystems and the prediction of solubilities for the quaternary system was made. Good agreement with published data was obtained.

Key words: PHASE EQUILIBRIUM, WATER, SOLUBILITY, QUATERNARY SYSTEM, POTASSIUM SULFATE, PHASE DIAGRAM, MAGNESIUM SULFATE, LITHIUM SULFATE
