METHOD OF EXTRACTING SILVER IONS FROM LOW-CONCENTRATION SILVER NITRATE SOLUTIONS

摘要

FIELD: chemistry.SUBSTANCE: method includes passing the solution through polymer fibre for sorption of silver ions. After passing the solution, silver ions contained in the fibre are reduced to a metal state with 0.02 M aqueous solution of a mixture of ascorbic acid with glucose in ratio of 1:9. Silver metal is then extracted by burning the silver-containing fibre in an air atmosphere at temperature of 450-500°C, followed by washing the formed silver reguli.EFFECT: recovering silver ions from industrial waste water, improved method of extracting silver from process solutions used when producing textile materials with antimicrobial properties.2 ex
