Alumino silica gel-AN

Nkọwa dị mkpirikpi:

Ọdịdị nke aluminomgel silicabụ obere odo ma ọ bụ ọcha transperent na chemical molekul usoro mSiO2 • nAl2O3.xH2O. Ngwongwo kemịkalụ kwụsiri ike. Enweghị ọkụ ọkụ, enweghị ike ịsacha n'ime ihe mgbaze ọ bụla ma e wezụga isi ike na hydrofluoric acid. E jiri ya tụnyere gel silica porous dị mma, ikike mgbasa ozi nke iru mmiri dị ala yiri (dịka RH = 10%, RH = 20%), mana ikike mgbasa ozi nke iru mmiri dị elu (dị ka RH = 80%, RH = 90%) bụ. 6-10% elu karịa nke ọma porous silica gel, na thermal kwụsie ike (350 ℃) bụ 150 ℃ elu karịa ezi porous silica gel. Ya mere, ọ bụ nnọọ adabara na-eji dị ka mgbanwe okpomọkụ adsorption na nkewa gị n'ụlọnga.
