Decontamination mechanism activated alumina

Activated alumina is a porous, high dispersion of solid materials, a large specific surface area and pore surface has strong adsorption and moisture absorption. Mechanism of decontamination more recently on activated alumina. but there are different views. To sum up, activated alumina price to remove impurities in the water (fluorine, for example) may be two ways: One is that activated alumina fluoride removal is the adsorption process; the other is that the activated alumina defluoridation is an ion exchange process. That metal in solution electrolysis of metal ions formed by ion exchange between a series of metal hydroxides and metal oxide hydrate polyhydroxy hydrated fluoride and aluminum oxide in water surface hydroxyl functional groups., Which to achieve the purpose of removal
