Today I want to share an article with you. The article is 《Solid-Liquid Equilibria (SLE) of the Quinary Reciprocal Aqueous System Li+, K+, Rb+//Cl–, Borate-H2O at 323.2 K》,you can find this article in 《Journal of Chemical & Engineering Data》. The following contents are mentioned:
The isothermal dissolution method was applied for the phase equilibrium experiment of the reciprocal quinary system Li+, K+, Rb+//Cl–, Borate-H2O at 323.2 K; the related d. (ρ) of the system was measured by the sp. gr. bottle method exptl., and the crystalloid forms of the equilibrated solid phase were identified by the X-ray diffraction method. Results show that the system belongs to a complex type with the formation of solid solution [(K, Rb)Cl]; six single salts, LiCl·H2O, KCl, RbCl, Li2B4O7·3H2O, K2B4O5(OH)4·2H2O, and RbB5O6(OH)4·2H2O, were also formed at 323.2 K; no double salt was found in this system. The space phase diagram consists of five quinary invariant points, fifteen isothermal dissolution curves, and seven crystallization fields. The size of the RbB5O6(OH)4·2H2O crystallization field is the largest among the coexisting salts in the quinary system. Under the condition of RbB5O8 saturation, the crystallization field of Li2B4O7·3H2O occupied the largest crystallization region, and salt RbCl had the smallest region. To complete the study, the researchers used Rubidiumchloride (cas: 7791-11-9) .
Rubidium chloride(cas: 7791-11-9) is the mostly used rubidium compound, and finds use in various fields ranging from electrochemistry to molecular biology.Safety of Rubidiumchloride It is an efficient non-invasive biomarker; increases dopamine and norepinephrine levels, and useful for anergic and apathetic depressives.
