Abstract
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°C within 16…18 hours.
