Macroporous adsorption resin ke mofuta oa polymer adsorption resin ntle le sehlopha sa phapanyetsano le sebopeho sa macroporous. E na le sebopeho se setle sa marang-rang le sebaka se seholo se holimo. E ka khetholla taba ea manyolo ka tharollo ea metsi ka ho hlahisa 'mele. Ke mofuta o mocha oa li-organic polymer adsorbent e ntlafalitsoeng lilemong tsa bo-1960. E 'nile ea sebelisoa haholo ho sireletsa tikoloho, lijo, meriana le likarolo tse ling.
Lera la macroporous adsorption hangata le na le likaroloana tse tšoeu tse chitja tse nang le boholo ba phatsa ea 20-60 mesh. Li-macrospheres tsa macroporous adsorption resin li entsoe ka likarolo tse ngata tse nyane tse nang le masoba.
Lera la macroporous adsorption le ne le silafalitsoe ka styrene, divinylbenzene, jj ka tharollo ea 0.5% ea gelatin le karolo e itseng ea porogen. Styrene e ne e sebelisoa e le monomer, divinylbenzene joalo ka crosslinking agent, toluene le xylene joalo ka porogens. Li ne li kopantsoe 'me li fetotsoe polasetiki ho theha sebopeho sa porous sa macroporous adsorption resin.
Ho khethoa ha maemo a ho qhekella le ho hlapolla ho ama ka kotloloho boleng ba ts'ebetso ea ts'ebetso ea adsorption ea lehoakhoa la macroporous, ka hona ho lokela ho nahanoa lintlha tse fapaneng ts'ebetsong eohle ho fumana maemo a matle ka ho fetisisa a adsorption le desorption. Ho na le lintlha tse ngata tse amang lehoakhoa adsorption, joalo ka thepa ea likarolo tse arohaneng (polarity le boholo ba limolek'hule), thepa ea ho kenya tharollo (solubility ea solvent ho likarolo, letsoai la letsoai le boleng ba pH), khatello ea tharollo ea tharollo le phallo ea metsi ea adsorption sekhahla.
Ka kakaretso, limolek'hule tse kholo tsa polar li ka aroloa ka lehare la polar le mahareng, mme limolek'hule tse nyane tsa polar li ka aroloa ka lehoakhoa le seng la polar; Ha boholo ba kompone bo le kholo, boholo ba pore ea resin bo kholoanyane; Bokhoni ba adsorption ba lehoakhoa bo ka eketsoa ka ho eketsa bongata bo nepahetseng ba letsoai le sa tsoeng ka har'a tharollo ea ho kenya; Lik'hemik'hale tse nang le asiti li bonolo ho tsejoa ka tharollo ea asiti, metsoako ea mantlha e bonolo ho phatlalatsoa ka tharollo ea alkaline, 'me metsoako e sa jeleng paate e bonolo ho phatlalatsoa tharollong e sa nke lehlakore; Ka kakaretso, ho theola mohopolo oa tharollo ea tharollo ho ntlafatsa tšebetso ea adsorption; Bakeng sa khetho ea sekhahla sa ho theoha, ho molemo ho netefatsa hore lehoakhoa le khona ho ikopanya ka botlalo le tharollo ea ho kenya bakeng sa adsorption. Lintho tse amang maemo a ho hlatsoa metsi li kenyelletsa mofuta oa eluent, mohopolo, boleng ba pH, sekhahla sa phallo, jj. The eluent e ka ba methanol, ethanol, acetone, ethyl acetate, jj. bokhoni ba lintho tse fapaneng lehoakhoeng; Ka ho fetola boleng ba pH ea eluent, mofuta oa molek'hule oa adsorbent o ka fetoloa, mme ho bonolo ho o hlaka; Sekhahla sa phallo ea elution ka kakaretso se laoloa ho 0.5-5ml / min.
Boholo ba pore le bokaholimo bo ikhethileng ba lehoakhoa la macroporous adsorption li batla li le kholo. E na le sebopeho sa pore se nang le mahlakore a mararo kahare ho lehoakhoa, se nang le menyetla e mengata joalo ka botsitso bo phahameng ba mmele le lik'hemik'hale, sebaka se seholo se ikhethileng, bokhoni bo phahameng ba adsorption, khetho e ntle, lebelo le potlakileng la adsorption, maemo a bonolo a ho hlatsuoa, nchafatso e bonolo, nako e telele potoloho ea ts'ebeletso, e loketseng potoloho e koetsoeng le ho boloka litšenyehelo.
