Alumina(A/B/N)ʻO ke kolamu hōʻiliʻili paʻa alumina / kolamu SPE

ʻO ka alumina he ʻakika lewis maʻamau, ʻAʻole ʻelua electrons i ke kikowaena atom alumini.He ikaika polar adsorbent, e like me ka silicone, Aia ekolu kiʻekiʻe pae hana o ka acidity, alkalinity a me ka neutrality;He hopena koʻikoʻi ko alumina i kaπelectrons o nā hydrocarbons aromatic, ʻoi aku ka maikaʻi ma mua o ke silicone i nā kūlana pH kiʻekiʻe.ʻO nā mīkini paʻa nui he lewis acid/base action, polarity a me ka hoʻololi ion.

alumina ʻakikaUa hoʻonui ʻia nā waiwai lewis acid o ka alumina-A (pH=4.5), ʻoi aku ka maikaʻi o kēia ʻano adsorbent no nā pūhui electron waiwai.Eia kekahi, i ka wā e hoʻomaʻamaʻa mua ʻia me ka hopena acidic, ʻo ka adsorbent i nāwaliwali nā waiwai cationic, ʻoi aku ka maikaʻi o ka mālama ʻana i nā mea kūʻokoʻa a me nā mea ʻino ʻole (e like me ka electroneutral a acidic anions), ʻAʻole hiki ke mālama i kahi uku maikaʻi. ʻO ka waiwai hoʻololi ion nāwaliwali. maʻalahi hoʻi ka mālama ʻana i nā mea hoʻoili ʻino.

alumina kumuPono ka ʻili o ka Alumina-B(pH=10) e mālama i nā mea i hoʻopaʻa ʻia i ka maikaʻi a i ʻole ka hydrogen.ʻO ka alumini oxide i mālama ʻia me ka hopena alkaline he mau waiwai anionic a me ka hana hoʻololi cationic.Eia kekahi, ʻoiai he ʻano o ka lewis base ka ʻili, hiki ke mālama ʻia no ka hāpana electron, e like me nā pūhui amine neutral.ʻOi aku ka haʻahaʻa o ka hiki no ka alumina neutral a acidic.Eia kekahi, hiki ke loaʻa ka paʻa hydrogen ikaika ma ka alumina-b, no laila ua maopopo ka hopena o ka hāpana polar cationic.

alumina kuʻunaʻO Alumina-N(pH=7.5) kekahi mea hoʻoheheʻe polar ikaika.Ma lalo o ke kūlana o ka pH kiʻekiʻe, ʻoi aku ka paʻa o ka alumina ma mua o ka hui hana unbonded.ʻO nā ʻāpana liʻiliʻi e hōʻoia i ka maikaʻi o ka unuhi ʻana, no laila ʻo kahi moena cylindrical liʻiliʻi (50mg) ka huahana maʻamau.ʻO ka adsorbent he uila kūʻokoʻa a mālama i nā pūhui uila waiwai e like me nā amine momona a momona.I ka manawa like, aia nō ka hiki ke mālama i nā pūhui i loaʻa nā pūʻulu electronegative e like me ka oxygen-containing, phosphorous and sulfur atoms.Hiki ke hoʻohana ʻia ʻo Alumina-N no ka unuhi ʻana a me ka hoʻokaʻawale ʻana o nā mea polar a i ʻole nā ​​mea polar i loko o ka wai-soluble a me ka wai ʻole.

Nā mea maikaʻi o ka huahana:

★ He kūpaʻa ka maikaʻi o ka huahana, hiki ke hana hou ʻia, hoʻouka i ka hoʻohālikelike maʻamau (RSD) < 5%.

★ Maʻemaʻe ka paʻi ʻana a ʻaʻohe mea hoʻopilikia ʻole ʻia.

★ He kiʻekiʻe ka helu hoʻihoʻi, a ʻo ka helu hoʻihoʻi o ka hoʻohui ʻana i ka hāpana 10 ~ 100ppm ʻo ia ka laulā maikaʻi loa o 95% ~ 105%.

★ ʻO ka hana kumukūʻai huahana kekahi o nā huahana maikaʻi loa o ka honua.
