METHOD FOR QUALITATIVE ANALYSIS OF SORPTION ACTIVITY OF AMINOACIDS Russian patent published in 1995 - IPC

Abstract RU 2030741 C1

FIELD: analysis of materials. SUBSTANCE: crushed apatite-nepheline ore and starch together with solution of rhodamine in 2-propanol are applied on adsorbent plate. Then drops of mixture of N-acylamino acids in alcohol as surface active substance (SAS) are applied on the plate and elution with mixture of chloroform/25% ammonia solution is carried out. Relative index Rf is determined after drying. Flotation activity is estimated is Rf(H)=0,70-0,95 and R(Na+)=0,05-0,35, where Rf(H) и Rf(Na) are acid and salt forms of mentioned above acids. EFFECT: improves efficiency of the method. 1 tbl
