White spherical porous granules with uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, non-swelling and non-cracking after water absorption, keep the original state, the product is non-toxic, tasteless, odorless, insoluble in water and organic solvents.

This product is used as a defluorinating agent for high fluorine water, and it is a kind of molecular adsorbent with huge specific surface area. When the PH value and alkalinity of raw water are low, the fluoride removal capacity is higher, which can be more than 3.0 mg/g, and the price is lower than that of synthetic resin. It can also be used to remove arsenic from drinking water. Particle size is generally larger contact area with water when used, and the specific surface area index is more than 300 m2/g. The large number of micropore can ensure the strong adsorption capacity of fluoride ions in water.
