This product is a kind of molecular adsorbent with large specific surface area, which is used as a fluoride removal agent of high fluoride water. When the PH value and alkalinity of the rawwater is low, the capacity of defluorination is high, which could be above 4.0mg/g. It can also be used to remove arsenic in the drinking water.

The partical size is 1-3mm, 2-4mm. When using it, the product has large contact area with water and specific surface area is higher than 310m2/g. It has a big quantity of micropores and can ensure strong adsorption and high defluorination volume to fluorinion in the water.
