Synthesis of mesoporous silica from geothermal water recycling system

摘要

To prevent the silica scale formation in the geothermal water recycling process, the silicic acid perfectly removed from geothermal water as calcium silicate by calcium nitrate. Ordered mesoporous silica was synthesized at strong acidic condition by using low cost calcium silicate as silicon source, which was separated from geothermal water recycling process.
