Alumina n'urusenda rwa molekile bisa (byombi biza mu ishusho ntoya y'umuzenguruko), bikora igikorwa kimwe (bikurura ibintu ku rwego rwa molekile), kandi byombi bifite ubushobozi bwo kongera kubyaza umusaruro (ushobora kongera kubikoresha iyo desiccant imaze kugera ku bushobozi) nyamara ni ibicuruzwa bibiri bitandukanye rwose. Ikibazo rero ni iki, hamwe n'ibintu byinshi bisa, bitandukanye bite?
Icyo bakorewemo ni ahantu heza ho gutangirira. Alumina ikora ikozwe muri aluminium oxide ifite imyenge myinshi, mu gihe molecule ikora muri crystalline metal alumino-silicate. Ibi bivuze ko imyenge iri kuri molecule ikora ishobora kugirwamo ingano runaka ikunze kugaragara nka 3A, 4A, 5A, na 13X, aho imyenge ya alumina ikora idafite ingano yihariye. Ibi bivuze ko molecule ikora ishobora gukoreshwa mu gutandukanya molecule zimwe na zimwe zifite ingano runaka, urugero nko gukuraho ammonia mu miyoboro ya gaze karemano.
Ukurikije uburyo bikoreshwa, dore uko bitandukanye. Alumina ikora ifite ubushobozi bukomeye bwo kwinjiza amazi, ishobora kwinjiza amazi menshi kurusha urusenda rwa molekile, ibi bituma iba igikoresho cy'ingirakamaro cyane mu byuma bikoresha umwuka cyangwa mu gutunganya gaze karemano. Kuba ibikoresho biramba bituma bihangana n'igitutu kinini hamwe n'ubushuhe bwinshi.
Alumina idakora ntishobora gukurura ubwoko bwinshi bw'ibintu cyangwa ngo itandukane na molekile zimwe na zimwe nk'uko utuyunguruzo twa molekile tubikora, bigatuma idakora neza mu buryo nk'ubwo kunywa ethanol. Ibi biterwa nuko alumina idakora ishobora gukurura molekile za ethanol n'amazi bityo nta gutandukana kwabayeho.
Urusenda rwa molekile rushobora kuba rudashobora kwinjiza amazi menshi ariko niba ukeneye kugabanya amazi kugeza ku gipimo gito cyane, kugeza kuri 0.1ppm, urusenda rwa molekile ni rwo rushobora kwinjiza amazi kuko iki ni ikintu izindi nganda zitashoboye kwinjiza amazi uretse urusenda rwa molekile.
Urusenda rwa molekile rushobora kandi gukoreshwa mu gutandukanya molekile runaka n'izindi, bitewe n'uburyo ingano yazo ihinduka. Urugero, ushobora gutandukanya amazi na ethanol, na dioxyde de carbone, ammonia, na hydrocarbon nini n'imigezi ya gaze karemano, ikintu alumina ikora idashobora gukora, cyangwa idashobora gukora neza kimwe.
