| 摘要 |
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. ^ 2 cl, 1 tbl, 4 ex |
