Umgaqo weiphepha lokufunxa ioyile yezimonyoIsekelwe ikakhulu kwizinto ezimbini ezibonakalayo: ukufunxwa kunye nokungena.
Okokuqala, umgaqo wokufunxa kukuba umphezulu wephepha elifunxa ioyile une-lipophilicity ethile, evumela ioyile ukuba ifunxeke ephepheni. Ukufunxa yinto ebonakalayo ebangelwa yinto edlula kumphezulu we-adsorbent. Umphezulu we-adsorbent unendawo enkulu ethile yomphezulu kunye nomsebenzi othile weekhemikhali, kwaye unokufunxa izinto ezijikelezileyo. Iifayibha zephepha elifunxa ioyile zigobile njenge-bamboo, kwaye imo kunye nomphezulu we-lumen zahlukile. Okukhona umphezulu umkhulu, kokukhona amandla okufunxa ioyile aqinileyo. Ezi fayibha zineempawu ze-hydrophobic kunye ne-lipophilic, ezenza iphepha elifunxa ioyile likwazi ukufunxa ioyile ngokufanelekileyo kumphezulu wobuso.
Okwesibini, umgaqo wokungena ngokungekho mthethweni kukubaiphepha elifunxa ioyileidla ngokusebenzisa indlela yokucubungula umphezulu osezantsi ukuze isithuba sayo sefayibha sibe sesifanelekileyo, yenze isenzo se-capillary, ukuze iphepha libe neempawu zokungena. Isenzo se-capillary sephepha sivumela ioyile ukuba isasazwe ngokulinganayo kwindawo yefayibha yephepha, kwaye isasazeke ngaphakathi ngesenzo se-capillary sephepha elijikelezileyo.
Ngamafutshane, iphepha elifunxa ioyile yobuhle lisusa ioyile yobuso egqithisileyo ngokusebenzisa izinto ezibonakalayo zokufunxa nokungena, ligcina ulusu lucocekile kwaye lucocekile.
