I-resin ye-macroporous adsorption yintlobo ye-resin ye-adsorption resin ngaphandle kweqela lokutshintshiselana kunye nesakhiwo se-macroporous. Inesakhiwo esihle senethiwekhi kunye nendawo enkulu ethile. Inokuthi ngokukhethekileyo ithengise into yendalo kwisisombululo esinamandla ngokusebenzisa intengiso yomzimba. Luhlobo olutsha lwe-adsorbent ye-organic polymer eyenziwe ngo-1960. Isetyenziswe ngokubanzi kukhuselo lokusingqongileyo, ukutya, amayeza kunye nezinye iinkalo.
I-resin ye-adsorption ye-Macroporous ngokuqhelekileyo i-white spherical particles kunye nobukhulu be-particle ye-20-60 mesh. I-macrospheres ye-macroporous adsorption resin yenziwe ngamanqanaba amancinci amancinci anemingxunya komnye komnye.
I-resin ye-macroporous adsorption yenziwa ipolymerized nge-styrene, i-divinylbenzene, njl. Kwi-0.5% isisombululo se-gelatin kunye nenxalenye ethile ye-porogen. I-Styrene yayisetyenziswa njenge-monomer, i-divinylbenzene njenge-arhente yokuqhekeza, i-toluene kunye ne-xylene njenge-porogens. Zadityaniswa zadityaniswa zenziwa ipolymer ukwenza ubume besakhelo se porous se-macroporous adsorption resin.
Ukukhethwa kwe-adsorption kunye ne-desorption iimeko ezichaphazela ngokuthe ngqo umgangatho wentengiso ye-macroporous adsorption resin, ke izinto ezahlukeneyo kufuneka ziqwalaselwe kuyo yonke inkqubo ukumisela eyona adsorption kunye neemeko zedisco. Zininzi izinto ezichaphazela i-resin adsorption, ezinje ngeepropathi zezinto ezahluliweyo (ubungakanani kunye nobungakanani bemolekyuli), iipropathi zokulayisha isinyibilikisi (ukunyibilika kwesinyibilikisi kwizinto, uxinzelelo lwetyuwa kunye nexabiso le-pH), uxinzelelo lokulayisha isisombululo kunye nokuhamba kwamanzi izinga.
Ngokubanzi, iimolekyuli ezinkulu ze-polar zinokwahlulwa kwi-resin ye-polar ephakathi, kwaye iimolekyuli ezincinci ze-polar zingahlulwa kwi-resin engeyiyo-polar; Umkhulu umthamo wekhompawundi, ubungakanani bepore bukhulu be-resin; Ubungakanani be-adsorption ye-resin bunokwandiswa ngokudibanisa inani elifanelekileyo leetyuwa ezingaphiliyo kwisisombululo sokulayisha; Iikhompawundi Acidic kulula ukuba adsorbed isisombululo asidi, iikhompawundi esisiseko kulula ukuba adsorbed isisombululo alkaline, kunye iikhompawundi cala kulula ukuba adsorbed kwisisombululo cala; Ngokubanzi, isezantsi uxinzelelo lokulayisha isisombululo, kokukhona kungcono ukubhengezwa kwentengiso; Ukukhetha inqanaba lokuyeka, kungcono uqiniseke ukuba i-resin inokunxibelelana ngokupheleleyo nesisombululo sokulayisha kwi-adsorption. Imiba echaphazela iimeko zokuphamba phakathi kubandakanya uhlobo lwe-eluent, uxinzelelo, ixabiso le-pH, inqanaba lokuhamba, njl njl. umthamo wezinto ezahlukeneyo kwi-resin; Ngokutshintsha ixabiso le-pH ye-eluent, ifom yeemolekyuli ze-adsorbent inokutshintshwa, kwaye kulula ukuyifumana; Umgangatho wokuhamba kwe-elution ulawulwa ngokubanzi kwi-0.5-5ml / min.
Ubungakanani bepore kunye nomgangatho othile wommandla we-macroporous adsorption resin mkhulu kakhulu. Inobume bepore ezintathu-ntathu ngaphakathi kwintlaka, enezinto ezininzi ezilungileyo ezinje ngokuzinza okuphezulu komzimba kunye neekhemikhali, indawo enkulu yomphezulu, umthamo omkhulu we-adsorption, ukukhetha okuhle, isantya se-adsorption ekhawulezileyo, iimeko zokuncitshiswa kobulali, ukuvuselelwa okufanelekileyo, ixesha elide Umjikelo wenkonzo, ulungele umjikelo wesekethe ovaliweyo kunye nokonga iindleko.
