Abstract:
A process for separating soluble silica species such as monomeric silicic acid (or monosilicic acid) and low molecular weight soluble polymeric silica from impure water soluble compounds by membrane nanofiltration is provided. A process for separating soluble silica species and colloidal silica from impure water soluble compounds by reverse phase liquid chromatography is also provided.
