COMPLEXING POLYIMIDE AS MATERIAL FOR SORPTION AND SEPARATION OF ALKALINE METAL IONS Russian patent published in 1994 - IPC

Abstract SU 1602023 A1

FIELD: high-molecular compounds, complexing alicyclic polyimides. SUBSTANCE: method involves the use of polyimides of the formula with molecular mass 50000-100000. Proposed polyimides show sorption capacity for ions of lithium, sodium, potassium, rubidium and cesium 1.0-1.2; 20.1-20.4; 70.0-70.4; 16.0-16.4 and 2.0-2.4 mg/g, respectively. Proposed polyimides can be used for separation of alkaline metal ions. EFFECT: enhanced sorption capacity of polyimides proposed. 1 tbl
