I roto i te hanga me te oranga, ka taea te whakamahi i te silica gel hei whakamaroke i te N2, te hau, te hauwai, te hau māori [1] me ētahi atu. E ai ki te waikawa me te kawakore, ka taea te wehewehe i te desiccant ki: te desiccant waikawa, te desiccant kawakore me te desiccant kūpapa [2]. Ko te silica gel te āhua nei he whakamaroke kūpapa e āhua nei ka whakamaroke i te NH3, HCl, SO2, me ētahi atu. Heoi, mai i te tirohanga matua, ko te silica gel he mea hanga mai i te whakamaroketanga i waenga i ngā ngota waikawa orthosilicic e toru-ahu, ko te tinana matua ko te SiO2, ā, he nui ngā rōpū hydroxyl o te mata (tirohia te Pikitia 1). Ko te take e taea ai e te silica gel te mimiti i te wai ko te mea ka taea e te rōpū hydroxyl silicon i runga i te mata o te silica gel te hanga hononga hauwai i waenga i ngā ngota wai, kia taea ai te mimiti i te wai, ā, kia whai wāhi ki te whakamaroke. Kei roto i te silica gel e huri-tae ana ngā iona cobalt, ā, i muri i te taenga o te wai adsorption ki te mākū, ka huri ngā iona cobalt i roto i te silica gel e huri-tae ana hei iona cobalt makuku, kia māwhero ai te silica gel kikorangi. I muri i te whakamahana i te tiēre silica māwhero i te 200℃ mō tētahi wā, ka motu te here hauwai i waenga i te tiēre silica me ngā ngota wai, ā, ka huri anō te tiēre silica kua ngaro te tae ki te kikorangi, kia taea ai te whakamahi anō i te hoahoa hanganga o te waikawa silicic me te tiēre silica e whakaaturia ana i te Pikitia 1. Nō reira, nā te mea he nui ngā rōpū hydroxyl i te mata o te tiēre silica, ka taea hoki e te mata o te tiēre silica te hanga hononga hauwai i waenga i ngā ngota ngota me te NH3 me te HCl, me ētahi atu, ā, kāore pea he huarahi hei whakamaroke i te NH3 me te HCl, ā, kāore he pūrongo e tika ana i roto i ngā tuhinga o nāianei. Nō reira, he aha ngā hua? Kua oti i tēnei kaupapa te rangahau whakamātautau e whai ake nei.
