Activated Alumina
Defluorination activated alumina uses high-purify AL2O3 as raw material, produced by complex processing, detydration, carbonization,
activation. It has smooth appearance, high mechanical strenth, stable chemical properties
(not dissolved in water & organic solvent), similar pellets, strong adsorption.
As a fine defluorination agent, it is a kind of molecular adsorbent with a huge surface area.
It can remove more than 3.0mg/g in a low PH value or low alkalinity conditions.
It is also used in drinking water and industrial equipment to remove F, As, color and smell.
The smaller of the diameter, the bigger of the surface area.
It has a big contact surface area with water at 1-3mm size.
The specific surface area can reach more than 260m2/g. A big pore volume can make sure
a high adsorption and a high defluorination.It can used with defluorination crock together.
It can apply to defluorination equipments. Such as, water supply equipment
and industrial equipment.
APPICATION1) Catalyst for recovering sulfur in the petrochemical industry;2) Excellent defluorination agent for drinking water and for recycling alkyl-hydrocarbon in alkylbenzene production;3) Reclaiming agent for de-acidic in transformer oil, and de-arsenic agent in the Acid industry ;4) Adsorbent in the production of hydrogen peroxide solution ;5) Catalyst for polyhydro-ammonia by substituting silica gel with ball-shaped product ;6) Desiccator and purifying agent.
