Molecular weight:102<molecular weight<117
(2). The products use alumina with high purity and are produced by scientific allocation and catalytic refining. They are white granules with globular porosity, epigranular, smooth surface, great mechanical strength, strong moisture absorption, no expansion and cracking but remain original shape when absorbing water and they are non-toxic, no smell, odorless and insoluble to water and organic solvents.
(3). They are used for high fluoride water and a kind of molecular adsorbent with great specific surface area.
(4). The fluoride removal agents can also be used with fluoride removal device of the waterworks and industry.

2. Desiccant activated alumina
(1). The products are white globular porosity particles with symmetrical particle size,
(2). They will remain original shape when absorbing water and they are non-poisonous, no smell, odorless and insoluble to water and organic solvents.
(3). It can be used as deacidificated regenerant of transformer oil and gas drying of oxygen industry, textile Industry and electronic industry, and air drying of automatic instrument and meter. It is also used as drying agent and cleaning agent in fertilizer and petrochemical industry (dew point reaches-40 degrees) and dew point reaches -55 degrees of pressure swing adsorption of space division industry.
