A cikin samarwa da rayuwa, ana iya amfani da gel silica don bushe N2, iska, hydrogen, iskar gas [1] da sauransu. A cewar acid da alkali, desiccant za a iya raba zuwa: acid desiccant, alkaline desiccant da tsaka tsaki desiccant [2]. Silica gel ya bayyana a matsayin na'urar bushewa mai tsaka-tsaki wanda alama ya bushe NH3, HCl, SO2, da dai sauransu Duk da haka, daga ra'ayi na ra'ayi, silica gel ya ƙunshi nau'i-nau'i uku na kwayoyin halitta na orthosilicic acid, babban jiki shine SiO2, kuma saman yana da wadata a cikin kungiyoyin hydroxyl (duba Hoto 1). Dalilin da yasa gel silica zai iya sha ruwa shine cewa ƙungiyar silicon hydroxyl a saman silica gel na iya samar da haɗin gwiwar hydrogen na intermolecular tare da kwayoyin ruwa, don haka yana iya shayar da ruwa kuma ta haka yana taka rawar bushewa. Gel ɗin silica mai canza launi yana ɗauke da ions cobalt, kuma bayan adsorption ruwa ya kai ga cikawa, ions cobalt a cikin gel ɗin silica mai canza launi ya zama hydrated cobalt ions, ta yadda gel silica blue ya zama ruwan hoda. Bayan dumama ruwan siliki mai ruwan hoda a 200 ℃ na ɗan lokaci, haɗin gwiwar hydrogen tsakanin silica gel da kwayoyin ruwa sun karye, kuma gel ɗin silica mai canza launin zai sake juya shuɗi, don haka za'a iya sake amfani da zane na silica acid da gel ɗin silica kamar yadda aka nuna a cikin Hoto 1. Don haka, tun da saman silica gel ɗin silica gellic na iya zama mai wadata a cikin rukunin silica gelyl na hydrogen. haɗin gwiwa tare da NH3 da HCl, da dai sauransu, kuma ba za a sami wata hanya ta yin aiki a matsayin mai lalata NH3 da HCl ba, kuma babu wani rahoto mai dacewa a cikin wallafe-wallafen da ake ciki. To mene ne sakamakon? Wannan batu ya yi bincike na gwaji mai zuwa.
