ʻO Alumina Hoʻāla ʻia no ka Hana ʻana i ka Wai

He mea keʻokeʻo poepoe ka huahana, he ʻano porous me ka waiwai ʻaʻohe ʻawahia, ʻaʻohe ʻala, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai a me ka ethanol. He like ka nui o ka ʻāpana, he laumania ka ʻili, kiʻekiʻe ka ikaika mechanical, ikaika ka hiki ke omo i ka makū a ʻaʻole e māhele ʻia ka pōpō ma hope o ke omo ʻana i ka wai.

Hiki i ka nui o ka ʻāpana ke 1-3mm, 2-4mm / 3-5mm a i ʻole ka liʻiliʻi e like me 0.5-1.0mm. Loaʻa iā ia kahi pili nui me ka wai a me ka ʻili kikoʻī ma mua o 300m² / g, he nui ka nui o nā microspores a hiki ke hōʻoia i ka adsorption ikaika a me ka nui defluorination kiʻekiʻe i ka fluorinnion i loko o ka wai.

He nui nā kahawai capillary a me ka ʻili ākea o ka alumina no ka hydrogen peroxide, hiki ke hoʻohana ʻia ma ke ʻano he adsorbent, desiccant a me catalyst. I ka manawa like, ua hoʻoholo ʻia hoʻi e like me ka polarity o ka mea i hoʻopili ʻia. Loaʻa iā ia kahi pilina ikaika no ka wai, nā oxides, ka acetic acid, alkali, a me nā mea ʻē aʻe. ʻO ka alumina i hoʻāla ʻia he ʻano desiccant hohonu micro-wai a he adsorbent no ka adsorbing polar molecules. .

Ma lalo o kekahi mau kūlana hana a me nā kūlana hana hou, ʻo kona hohonu maloʻo e like me ke kiʻekiʻe o ka mahana o ka hau ma lalo o -40 ℃, a he desiccant kūpono ia no ka hoʻomaloʻo hohonu ʻana o ka wai trace. Hoʻohana nui ʻia ia i ka hoʻomaloʻo ʻana i ke kinoea a me ka wai o ka ʻoihana petrochemical, ka hoʻomaloʻo ʻana o ka ʻoihana lole, ka ʻoihana hana oxygen a me ka ea mea hana aunoa, ka adsorption swing pressure i ka ʻoihana hoʻokaʻawale ea, a pēlā aku. Ma muli o ka wela kiʻekiʻe o ka papa adsorption monomolecular, kūpono loa ia no nā mea hana hou wela ʻole. ʻO Alumina no ka hydrogen peroxide he mau ʻāpana porous spherical keʻokeʻo me ka nui o nā ʻāpana like, ka ʻili laumania, ka ikaika mechanical kiʻekiʻe a me ka hygroscopicity ikaika. Hana ʻia ia me ka alumina maʻemaʻe kiʻekiʻe ma o ka hoʻomākaukau ʻepekema a me ka hoʻopau catalytic. Hiki ke hoʻohana ʻia ma ke ʻano he mea wehe fluoride no ka wai fluoride kiʻekiʻe, e lilo ia i adsorbent molecular me kahi ʻili kikoʻī nui. Ke haʻahaʻa ka waiwai pH a me ka alkalinity o ka wai maka, kiʻekiʻe ka hiki ke wehe i ka fluorine, ʻoi aku ma mua o 3.0mg/g. Hiki ke hoʻohana ʻia no ka wehe ʻana i ka fluorine, ka wehe ʻana i ka arsenic, ka decolorization sewer a me ka deodorization o ka wai inu a me nā mea hana ʻoihana.
