METHOD OF PRODUCING COMPLEXING SORBENT (VERSIONS) AND USE THEREOF FOR X-RAY FLUORESCENCE DETERMINATION OF HEAVY METALS IN WATER Russian patent published in 2013 - IPC B01J20/281 B01J20/32 G01N33/18 G01N23/223

Abstract RU 2472582 C1

FIELD: chemistry.

SUBSTANCE: invention relates to analytical chemistry. Disclosed is a complexing sorbent which is obtained by impregnating the surface of cellulose filters with organic complexing reagents selected from thiophene-2-carbaldehyde thiosemicarbazone or 5-nitrothiophene-2-carbaldehyde thiosemicarbazone. The sorbent is efficient for concentrating heavy metals from solutions for subsequent X-ray fluorescence determination.

EFFECT: obtaining a sorbent having high sorption capacity for a wide range of aliovalent ions and capacity for both individual and group extraction of heavy metals.
