ABSTRACT
In the study application of the macroporous ionite, Amberlyst® 15 (Merck), was tested in the process of production of dilute solutions of silicic acid sols. The process of ion exchange was conducted in a periodic reactor employing batch technique at the temperature of 45oC or 85oC. The products involved clear and stable solutions of sols of mean SiO2 concentrations of 4.31, 4.72, 6.34 and 6.46 wt.%. A two-stage technique for ionite recovery was also worked out.
