Kafirin yog lub ntuj tsim, hydrophobic thiab celiac muaj kev nyab xeeb prolamin protein tau los ntawm sorghum noob.Niaj hnub no kafirin tau pom tias muaj txiaj ntsig zoo hauv kev tsim cov khoom xa tawm qeeb thiab txheej txheej ntawm cov tshuaj thiab cov khoom noj uas nws cov purity tseem ceeb thiab qhov no tuaj yeem tau txais los ntawm adsorptive chromatography.Txoj kev tshawb no yog thawj qhov kev pom kev tshawb fawb rau hauv isotherm thiab kinetic kev tshawb fawb ntawm kafirin adsorption ntawm anion- thiab cation-exchange resins rau kev siv tswv yim hauv kev npaj scale chromatography.Adsorption isotherms ntawm kafirin tau txiav txim siab rau tsib anion- thiab ob cation-exchange resins hauv batch systems.Isotherm tsis xws li qhov siab tshaj plaws binding peev thiab dissociation tas li tau txiav txim los ntawm Langmuir isotherm, thiab adsorptive muaj peev xwm thiab affinity tas li los ntawm Freundlich isotherm.Langmuir isotherm tau pom kom haum cov ntaub ntawv adsorption equilibrium zoo.Batch uptake kinetics rau kafirin adsorption ntawm cov resins kuj tau ua tiav thiab qhov tseem ceeb tsis muaj xws li cov diffusion coefficient, zaj duab xis loj hloov coefficient, thiab Biot tooj rau zaj duab xis-pore diffusion qauv raug xam.Ob qho tib si isotherm thiab cov kinetic tsis tau txiav txim siab rau kev xaiv cov resin tsim nyog rau kev ua kom huv si kafirin.UNOsphere Q (78.26 mg / ml) thiab Toyopearl SP-650M (57.4 mg / ml) tau pom tias muab cov kafirin khi muaj peev xwm zoo dua thiab kev sib cuam tshuam lub zog nrog kev txhawb nqa kinetics zoo nyob rau hauv kev ua haujlwm nruab nrab.Nrog rau cov adsorbents no, zaj duab xis diffusion kuj tau pom tias yog qhov tseem ceeb tshaj plaws rau adsorption (Bi<10 thiab δ<1).Raws li tus tsim lub hom phiaj muaj nuj nqi, UNOsphere Q tau pom tias yog qhov zoo tshaj plaws adsorbent rau kev khi ntawm kafirin.Cov ntaub ntawv nthuav tawm yog qhov tseem ceeb rau kev tsim cov nplai loj npaj adsorptive chromatographic kafirin purification systems
