Abstract

Procedeul de separare a bariului din compusii de strontiu solubili în apa si, de preferinta din halogenuri de strontiu, respectiv din SrCl2, conform inventiei, realizeaza tratarea solutiilor sarurilor de strontiu cu solutie de acid sulfuric pâna la 2 molara si, de preferinta, pâna la 0,5 molara si cu saruri bazice de strontiu ce pot fi alese între SrCO3, SrO si/sau Sr(OH)2 . nH2O, unde n = 0...8 si, de preferinta Sr(OH)2 . 8H2O, tratarea având loc în flux continuu sau discontinuu, reactantii putând fi introdusi în solutia de saruri de strontiu supusa tratarii simultan sau în cicluri succesive.
