Alumina Adsorbent No ka Hydrogen Peroxide

ʻO ka huahana he mea keʻokeʻo, spherical porous mea me ka waiwai o ka non-toxic, odorless, insoluble i ka wai a me ka ethanol. He ʻano like ka nui o ka ʻāpana, ʻoluʻolu ka ʻili, kiʻekiʻe ka ikaika mechanical, ikaika ka hiki o ka hoʻoheheʻe ʻana i ka wai a ʻaʻole i ʻoki ʻia ka pōleʻa ma hope o ka lawe ʻana i ka wai.

ʻO ka alumina no ka hydrogen peroxide he nui nā kaila capillary a me kahi ākea nui, hiki ke hoʻohana ʻia e like me adsorbent, desiccant a me catalyst. I ka manawa like, ua hoʻoholo ʻia e like me ka polarity o ka mea adsorbed. He pilina ikaika kona no ka wai, oxides, acetic acid, alkali, etc. Activated alumina he ʻano micro-water deep desiccant a me ka adsorbent no ka adsorbing polar mole. .

Ma lalo o kekahi mau kūlana hana a me nā kūlana hana hou, ʻo kona hohonu maloʻo he kiʻekiʻe e like me ka mahana o ka hau ma lalo o -40 ℃, a he desiccant maikaʻi ia no ka hoʻomaloʻo hohonu ʻana i ka wai. Hoʻohana nui ʻia ia i ke kinoea a me ka wai hoʻomaloʻo ʻana o ka ʻoihana petrochemical, hoʻomaloʻo ʻana i ka ʻoihana textile, oxygen production ʻoihana a me ka ea mea kani ʻakomi, kaomi kowali adsorption i ka ʻoihana hoʻokaʻawale ea, a me nā mea ʻē aʻe. He kūpono loa ia no nā mea hana hou ʻole wela. ʻO ka alumina no ka hydrogen peroxide he mau ʻāpana porous spherical keʻokeʻo me ka nui o nā ʻāpana like ʻole, ka ʻili laulima, 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 hoʻohemo fluoride no ka wai fluoride kiʻekiʻe, e hoʻolilo iā ia i adsorbent molecular me kahi ʻāpana kikoʻī nui. Ke haʻahaʻa ka pH waiwai a me ka alkalinity o ka wai maka, ʻoi aku ka nui o ka hiki ke hoʻoneʻe 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 a me ka deodorization o ka wai inu a me nā mea hana ʻoihana.
