Fig. 3: Quantitative composition of the solid precipitates for synthetic solution.

Compositions obtained before (A, B) and after (C, D) the basic treatment of synthetic hypersaline solution at different temperatures, in terms of crystalline phases detected by PXRD (A, C) and corresponding relative elemental composition (excluding C, O and H atoms) (B, D) in the starting solution (Feed), recovered crystals (Cryst.) and mother solution after removal of crystals by filtration (Ret.).
