It is proposed that the process of removing fluorine with activatedalumina is inappropriate to be termed as adsorption or ion exchanging, as lots of tests have shown.
通过大量的试验证明，活性氧化铝除氟不能简单归结为分子吸附或离子交换，要考虑具体的工艺过程。

At the same time, the effect of the concentration of sodium metaaluminate and regeneration time on the defluoridation capacity of activatedalumina after being regenerated has been studied.
同时研究了偏铝酸钠浓度、再生时间对再生后的活性氧化铝的除氟效能的影响。

The pollutants of tail gas, sewage, waste activatedalumina, etc, in the hydrogen peroxide production by anthraquinone process are introduced. Their recovery treatment methods are put forward.
