Process for modification with Al(III) compounds of the reticulate ionogenic polymers containing R4N+ groups

摘要

The invention relates to a process for obtaining of ion-exchange resins modified with metal compounds, and may be used in the substance sorption, separation processes and in the catalysis. The process consists in that the polymers are treated with a solution of alum or aluminum sulphate, containing 13,0...17,0 g/L Al(III) with pH 3,4...3,5, in the ratio of 0,2...0,5 g of polymer to 100 mL of solution, at the temperature of 80...90 degree C within 16...18 hours.Claims: 1
