METHOD OF REMOVING IONS OF CONTAMINATING METALS FROM FLOWS OF LIQUIDS Russian patent published in 2001 - IPC

FIELD: method of removing contaminating metal ions from liquid flows. SUBSTANCE: method includes contacting of liquid flow with novel crystalline molecular sieve under conditions of absorption. Novel crystalline molecular sieve has crystalline structure which presents aggregate of structures of pharmacosiderite and sitinakite. Molecular sieve has formula A_((4-4x)/n)(M_xTi_l-zGe_y)₄(Ge_l-pSi_p)_qO_r, where A presents cation such as cation of sodium or potassium, and M is metal such as niobium or titanium. EFFECT: efficient removal of cesium and strontium ions from water flows. 7 cl, 3 dwg, 5 ex
