Alumino silica gel-AN

Tlhaloso e Khutšoanyane:

Ponahalo ea aluminiumgel ea silikae 'mala o mosehla kapa o mosoeu o bonaletsang ka mokhoa oa lik'hemik'hale oa molek'hule mSiO2 • nAl2O3.xH2O. Thepa e tsitsitseng ea lik'hemik'hale. Ha e chese, ha e qhibilihe ka har'a motsoako ofe kapa ofe ntle le setsi se matla le hydrofluoric acid. Ha ho bapisoa le gel e ntle ea silica gel, matla a adsorption a mongobo o tlase a tšoana (joalo ka RH = 10%, RH = 20%), empa matla a adsorption a mongobo o phahameng (joalo ka RH = 80%, RH = 90%) ke 6-10% e phahameng ho feta ea gel e ntle ea porous silika, le botsitso ba mocheso (350 ℃) ke 150 ℃ e phahameng ho feta gel e ntle ea porous silika.
