I-resin ye-macroporous adsorption iyinhlobo ye-polymer adsorption resin ngaphandle kweqembu lokushintshana nesakhiwo se-macroporous. Inesakhiwo esihle senethiwekhi enkulu nendawo enkulu ethize. Ingakhetha ngokukhethekile udaba lwezinto eziphilayo kusisombululo esinamanzi ngokukhishwa kwe-adsorption ngokomzimba. Luhlobo olusha lwe-organic polymer adsorbent eyakhiwa ngawo-1960. Isetshenziswe kabanzi ekuvikelweni kwemvelo, ekudleni, emithini nakweminye imikhakha.
I-resin ye-macroporous adsorption ngokuvamile imhlophe izinhlayiya eziyindilinga ngosayizi wezinhlayiyana ezingama-20-60 mesh. Ama-macrospheres we-macroporous adsorption resin akhiwa ama-micro sphere amaningi anezimbobo komunye nomunye.
I-resin ye-macroporous adsorption yenziwa yapholishwa nge-styrene, i-divinylbenzene, njll ku-0.5% solution ye-gelatin kanye nenani elithile le-porogen. Isitayela sasetshenziswa njenge-monomer, i-divinylbenzene njenge-ejenti yokuxhumanisa, i-toluene ne-xylene njengama-porogens. Zinqanyulwe zafakwa amakholomu ukuze zenze uhlaka olunamandla lwe-resin ye-macroporous adsorption.
Ukukhethwa kwe-adsorption kanye ne-desorption izimo kuthinta ngqo ikhwalithi yenqubo yokukhangisa ye-macroporous adsorption resin, ngakho-ke izinto ezahlukahlukene kufanele zicatshangelwe kuyo yonke inqubo ukuthola izimo zokukhishwa kwe-adsorption nezokususa okuhle kakhulu. Kunezici eziningi ezithinta i-resin adsorption, njengezakhiwo zezinto ezihlukanisiwe (ubukhulu kanye nosayizi wamangqamuzana), izakhiwo zokulayisha kuphela (ukuncibilika kwe-solvent kuzinto, ukugxila kasawoti kanye nenani le-pH), ukugxila kwesisombululo sokulayisha kanye nokugeleza kwamanzi kwe-adsorption isilinganiso.
Ngokuvamile, ama-molecule amakhulu we-polar angahlukaniswa ku-resin esezingeni eliphakathi nendawo, futhi ama-molecule amancane we-polar angahlukaniswa ku-resin engeyona eye-polar; Kukhula ivolumu yenkomponi, kukhula usayizi wepore we-resin; Amandla we-adsorption we-resin angakhuphuka ngokungeza inani elifanele likasawoti wezinto ezingafani nesisombululo sokulayisha; Amakhemikhali e-Acidic kulula ukufakwa ku-acidic solution, izinhlanganisela eziyisisekelo kulula ukufakwa ku-solution ye-alkaline, futhi izinhlanganisela ezingathathi hlangothi kulula ukukhishwa ku-solution engathathi hlangothi; Ngokuvamile, ukwehla kokuhlushwa kwesixazululo sokulayisha, kungcono kakhulu ukukhangisa; Ngokukhetha izinga lokwehla, kungcono ukuqinisekisa ukuthi i-resin ingaxhumana ngokuphelele nesisombululo sokulayisha se-adsorption. Izici ezithinta izimo zokudonswa kwamanzi zifaka phakathi uhlobo lwe-eluent, ukugxila, inani le-pH, isilinganiso sokugeleza, njll. I-eluent ingaba yi-methanol, i-ethanol, i-acetone, i-ethyl acetate, njll. umthamo wezinto ezahlukahlukene ku-resin; Ngokushintsha inani le-pH le-eluent, ifomu lamangqamuzana le-adsorbent lingaguqulwa, futhi kulula ukulichaza; Izinga lokugeleza kwe-elution ngokuvamile lilawulwa ku-0.5-5ml / min.
Usayizi wepore kanye nendawo ethile engaphezulu ye-macroporous adsorption resin mikhulu kakhulu. Inezinhlaka ezintathu ezinamacala amathathu wepore ngaphakathi kwe-resin, enezinzuzo eziningi njengokuqina okuphezulu komzimba namakhemikhali, indawo enkulu ethize, umthamo omkhulu we-adsorption, ukukhetha okuhle, isivinini se-adsorption esisheshayo, izimo ezimuncu zokwehliswa, ukuvuselelwa okulula, isikhathi eside umjikelezo wesevisi, ofanele umjikelezo wesifunda ovaliwe nokonga izindleko.
