ʻO ka resrop adsorption Macroporous kahi ʻano o ka resin adsorption polymer me ka hui ʻole o ka hui a me ka macroporous. Loaʻa iā ia kahi ʻōnaehana macroporous maikaʻi a me kahi ākea kikoʻī nui. Hiki iā ia ke koho adsorb i nā mea kūlohelohe i ka hopena wai ma o ka adsorption kino. He ʻano hou ia o ka meaola polymer adsorbent i hoʻomohala ʻia i nā makahiki 1960. Ua hoʻohana ākea ʻia ia i ka pale ʻana i ke kaiapuni, nā meaʻai, nā lāʻau a me nā māla ʻē aʻe.
ʻO ka resrop adsorption Macroporous he keʻokeʻo ākea ākea me ka nui o 20-60 hei. Hoʻokumu ʻia nā macrospheres o ka macroporous adsorption resin i loko o nā spheres micro he nui me nā lua o kekahi.
Ua polymerized ka resrop adsorption Macroporous me styrene, divinylbenzene, a me nā mea ʻē aʻe i ka 0.5% gelatin solution a me kekahi mahele o ka porogen. Ua hoʻohana ʻia ʻo Styrene ma ke ʻano he monomer, divinylbenzene ma ke ʻano he crosslinking agent, toluene a me xylene ma ke ʻano he porogens. Hoʻohui ʻia a polymerized ʻia lākou e hana i ke ʻano porous framework o ka macroporous adsorption resin.
ʻO ke koho ʻana o nā adsorption a me nā kūlana desorption e hoʻopili pololei i ka maikaʻi o ke kaʻina adsorption o ka resor adsorption macroporous, no laila pono e noʻonoʻo ʻia nā mea like ʻole i ke kaʻina holoʻokoʻa e hoʻoholo i nā kūlana adsorption maikaʻi a me nā desorption. Nui nā kumu e hoʻopili ana i ka adsorption resin, e like me nā waiwai o nā ʻāpana i hoʻokaʻawale ʻia (polarity a me ka nui o ka mole), nā waiwai o ka hoʻoheheʻe ʻana i ka solvent (solubility of solvent i nā ʻāpana, ka paʻakai paʻakai a me ka waiwai pH), ka hoʻoliʻiliʻi o ka hoʻouka ʻana i ka hopena a me ka kahe wai adsorption. uku paneʻe.
ʻO ka mea maʻamau, hiki ke hoʻokaʻawale ʻia nā mole polar nui aʻe ma ka resin polar medium, a hiki ke hoʻokaʻawale ʻia nā mole polar liʻiliʻi ma ka resin non-polar; ʻO ka nui o ka nui o ka hui, ʻo ka nui o ka nui o ka pore o ka kēpau; Hiki ke hoʻonui ʻia ka māka adsorption o ke kēpau ma o ka hoʻohui ʻana i ka nui o ka paʻakai inorganic i loko o ka hopena hoʻouka; Maʻalahi e hoʻolaha ʻia nā hui waikawa ma ka hopena acidic, maʻalahi e hoʻopili ʻia i nā wai kūmole i loko o ka hopena alkaline, a maʻalahi hoʻi e hoʻopili ʻia nā mea kūleʻa ʻole i ka hopena kūpaʻa; ʻO ka maʻamau, ʻo ka hoʻohaʻahaʻa o ka hoʻouka ʻana i ka hopena, ʻoi aku ka maikaʻi o ka adsorption; No ke koho ʻana o ka helu hāʻule, ʻoi aku ka maikaʻi e hōʻoia i ka resin hiki ke hoʻopili piha me ka hopena hoʻouka no ka adsorption. ʻO nā kumuhana e pili ana i nā kūlana desorption e pili ana i ke ʻano o eluent, concentration, pH waiwai, kahe kahe, a pēlā aku. Hiki i ka eluent ke methanol, ethanol, acetone, ethyl acetate, a pēlā aku. hiki i nā mea ʻokoʻa ma ke kēpau; Ma ka hoʻololi ʻana i ka waiwai o ka pH o ka eluent, hiki ke hoʻololi ʻia ke ʻano molaki o ka adsorbent, a maʻalahi hoʻi ke elute; ʻO ka nui o ke kahe elution e kaohi ʻia ma 0.5-5ml / min.
ʻO ka nui o ka pore a me kahi o kahi o ka macroporous adsorption resin nui. Loaʻa iā ia he ʻekolu dimensional pore pore ʻona i loko o ka kēpau, nona nā pono he nui e like me ke kūpaʻa o ke kino a me ke kemika, kahi ʻāpana kikoʻī nui, hiki i ka adsorption nui, selectivity maikaʻi, wikiwiki adsorption wikiwiki, nā kūlana desorption māmā, hoʻoponopono hou, lōʻihi pōʻaiapuni lawelawe, kūpono no ka pōʻaiapuni paʻa a me ka mālama kālā ʻana.
