Dab tsi yog qhov cuam tshuam ntawm pH ntawm kev tshem tawm tus nqi, kev tsim kho dej thiab daim nyias nyias lub neej?

Tus coj pH ntau ntawm rov qab osmosis membrane cov khoom lag luam feem ntau 2-11. pH muaj cov nyhuv me me ntawm cov ntawv kawm membrane. Qhov no yog ib qho ntawm cov yam ntxwv tseem ceeb txawv ntawm lwm cov khoom tsim membrane. Txawm li cas los xij, cov yam ntxwv ntawm ntau ions hauv dej cuam tshuam loj heev los ntawm pH. Piv txwv li, thaum cov kua qaub qaug zog xws li citric acid feem ntau tsis-ionic nyob rau hauv qis pH tej yam kev mob, lawv cais thiab ua ionic nyob rau hauv pH siab. Vim tias cov qub ion muaj qhov ntsuas siab, qhov tshem tawm ntawm daim nyias nyias yog qhov siab, thiab tus nqi tshem tawm ntawm daim nyias nyias yog tsawg yog tias tus nqi them yog tsawg lossis tsis muaj nqi. Yog li no, pH muaj qhov cuam tshuam loj heev ntawm kev tshem tawm tus nqi ntawm qee qhov impurities.
