A cikin samarwa da rayuwa, ana iya amfani da gel ɗin silica don busar da N2, iska, hydrogen, iskar gas [1] da sauransu. Dangane da acid da alkali, ana iya raba desiccant zuwa: acid desiccant, alkaline desiccant da neutral desiccant [2]. Gel ɗin silica ya bayyana a matsayin na'urar busar da kai wadda take kama da busar da NH3, HCl, SO2, da sauransu. Duk da haka, daga mahangar asali, gel ɗin silica ya ƙunshi bushewar ƙwayoyin orthosilicic acid masu girma uku, babban jiki shine SiO2, kuma saman yana da wadataccen rukunin hydroxyl (duba Hoto na 1). Dalilin da yasa gel ɗin silica zai iya sha ruwa shine cewa ƙungiyar silicon hydroxyl da ke saman gel ɗin silica na iya samar da haɗin hydrogen na intermolecular tare da ƙwayoyin ruwa, don haka yana iya sha ruwa don haka yana taka rawar bushewa. Gel ɗin silica mai canza launi yana ɗauke da ions na cobalt, kuma bayan ruwan sha ya kai ga cikawa, ions na cobalt a cikin gel ɗin silica mai canza launi suna zama ions na cobalt mai ruwa, don haka gel ɗin silica mai shuɗi ya zama ruwan hoda. Bayan dumama gel ɗin silica mai ruwan hoda a zafin 200℃ na wani lokaci, haɗin hydrogen tsakanin gel ɗin silica da ƙwayoyin ruwa ya karye, kuma gel ɗin silica mai launin zai sake yin shuɗi, ta yadda za a iya sake amfani da zane-zanen silicic acid da gel ɗin silica kamar yadda aka nuna a Hoto na 1. Don haka, tunda saman gel ɗin silica yana da wadataccen rukunin hydroxyl, saman gel ɗin silica na iya samar da haɗin hydrogen tsakanin molecular tare da NH3 da HCl, da sauransu, kuma wataƙila babu wata hanyar da za a iya yin aiki a matsayin mai lalata NH3 da HCl, kuma babu wani rahoto mai dacewa a cikin wallafe-wallafen da ke akwai. To menene sakamakon? Wannan mutumin ya yi binciken gwaji mai zuwa.
