METHOD OF METAL ION RECOVERY FROM SOLUTIONS Russian patent published in 2009 - IPC C02F1/42 C02F1/28 C02F1/62 B01J39/08 C02F103/16 B01J20/26 B01J39/20

Abstract RU 2350567 C1

FIELD: chemistry.

SUBSTANCE: cation exchanger is a modification product of rubber powder produced with acrylic acid engrafted into rubber powder. Rubber powder is prepared with gaseous nitric oxides at temperature 25-50°C. Acid number of end product is 8.74-12.04 mg KOH/g. Ground tread rubber of particle size 0.125-1.0 mm is preferable as rubber powder.

EFFECT: higher sorptive capacity of cation exchanger, increased number of sorbed ions.
