WYA-9100、9101 Special adsorbent for hydrogen peroxide
1.Chemical formula:Al₂O₃·nH₂O n<0.5
2.Properties and uses
This series of products is γ-form aluminum oxide with white or pinkish red spherical particle.It is produced from the intermediate product as raw material,which is obtained by quick dehydration method.It has the advantages of high strength,insoluble in water,hydrocarbon,alcohol andester etc.organic solvent,non-powdering and non-softening in the water,high clarifying degree,long service life,non-toxic,tasteless,odourless and powerful degradation and regeneration abilities to anthraquinone derivant.It is a special adsorbent for hydrogen peroxidemade by anthraquinone method.This series of products has not only the ability of adsorption alkali in working solution,but also has strongregenerating ability to degradation products.So it has an important effect on decreasing the consumption of anthraquinone and stabilize working solution.The quality ofthe product is in the leading level of similar products in China.
