This project will compile and evaluate all available solubility data in binary and higher component aqueous systems with lithium sulfate, but excluding organic solvents. The results of this work will be prepared in the standard format of the IUPAC-NIST Solubility Data Series for publication in the Journal of Physical and Chemical Reference Data and for inclusion in a web-accessible database being prepared by the US National Institute of Standards and Technology (NIST).




Under the direction of the Subcommittee on Solubility and Equilibrium Data (SSED) of the Analytical Chemistry Division , the IUPAC Solubility Data Project (SDP) compiles and evaluates data on solubility and disseminates the resulting information to the widest possible range of users by traditional (printed)  and electronic (web-accessible database) means.

The Solubility Data Project is focused  on five subject areas of wide importance. The systems to be covered by this project fit into one of these priority areas, Solubility Related to Industrial Processes. Lithium sulfate plays an important role in the recovery of lithium salts. The vast increasing demand for lithium carbonate and other lithium compounds world-wide for applications particularly in battery productions, requires the development of more efficient recovery processes from the various lithium resources. The most important processes use salt lake brines as lithium resource. In most of these cases a sustainable and effective lithium recovery is connected with an appropriate management of sulfate/lithium ratios combined with other salts in order to avoid lithium loss due to sulfate crystallization. On the other side formation of lithium sulfate or its double salts can be used to develop also new separation processes. The respective systems were not covered yet in Solubility Data Series. There exists an enormous demand for compact and reliable solubility data collections of lithium compounds. This project will concentrate on one important class of these compounds.
