METHOD OF OBTAINING THE METAL-CONTAINING CARBON-CHAIN SORPTION-ACTIVE FIBER Russian patent published in 1995 - IPC

Abstract SU 1816006 A1

FIELD: medical engineering. SUBSTANCE: raw polyvinyl alcohol fiber containing 5-6 millimoles/gram of carboxyls is impregnated first with nickel ammoniate with the nickel concentration of 3 - 4 grams/liter at 15-20 C during 5 - 10 min. pH of the medium 13 - 14 is specified by sodium hydroxide. Then it is processed by 85-98% water solution of hydrate hydrazine at 90-98 C for 30-40 min. EFFECT: enhanced separation of the proteins of the allantoic liquid and enhanced sorption capacity in relation to them. 1 tbl
