ungasebenzisa i-centrifugation ukwahlula amanzi nesanti

Intshayelelo

I-Centrifugation yindlela esetyenziswa kakhulu kwiinkalo ezahlukeneyo zesayensi equka ukwahlula imixube ngokusekelwe kubuninzi bayo kusetyenziswa amandla e-centrifugal. Kweli nqaku, siza kuhlola ukuba i-centrifugation ingasetyenziswa ngokufanelekileyo na ukwahlula amanzi nesanti. Siza kungena kwimigaqo ye-centrifugation, iimpawu zamanzi nesanti, size sixoxe ngemingeni kunye nezisombululo ezinokubakho zokwahlula ngempumelelo ezi zinto zimbini. Ngoko masiqale!

Ukuqonda i-Centrifugation

Ngaphambi kokuba sijonge ukwahlula amanzi nesanti sisebenzisa i-centrifugation, kubalulekile ukuqonda imigaqo esisiseko yale ndlela. I-centrifugation isebenza ngokujikelezisa isampuli ngesantya esiphezulu, nto leyo evelisa amandla e-centrifugal atyhala amasuntswana ukuba awahlukanise ngokusekelwe kubuninzi bawo. Amasuntswana anzima athanda ukuya kumda ongaphandle wegumbi lokujikelezisa, ngelixa amasuntswana alula anokuhlala kufutshane nombindi.

Iipropati zamanzi nesanti

Amanzi, isinyibilikisi esibalulekileyo nesiqhelekileyo, anoxinano olumalunga ne-1 gram nge-cubic centimeter (g/cm³) kubushushu begumbi. Liyimolekyuli ye-polar, nto leyo eyenza ukuba ibe yindawo efanelekileyo yokunyibilikisa nokuthutha izinto ezahlukeneyo. Kwelinye icala, isanti ikakhulu ine-silicon dioxide (SiO₂) kwaye inoxinano oluphezulu kakhulu xa kuthelekiswa namanzi, umyinge umalunga ne-2.65 g/cm³.

Imingeni yoKwahlula Amanzi neSanti

Ukwahlulwa kwamanzi nesanti kubeka umceli mngeni omkhulu ngenxa yokwahluka koxinano lwazo, njengoko amasuntswana esanti exinene kakhulu kunamanzi. Xa exutyiwe, amasuntswana esanti adla ngokutshona ngokukhawuleza, nto leyo eyenza ukuba iindlela eziqhelekileyo zokuhluza okanye zokuthungela amanzi zingaphumeleli. Ukujongana nale ngxaki kufuna ukusetyenziswa kwe-centrifugation, phakathi kwezinye iindlela ezinokubakho, ukuze kufunyanwe ukwahlulwa okusebenzayo.

Ukusebenzisa iCentrifugation Ukwahlula Amanzi Nesanti

Ukwahlula amanzi nesanti kusetyenziswa i-centrifugation, kufuneka kulandelwe amanyathelo ambalwa abalulekileyo. Masixoxe ngala manyathelo ngokweenkcukacha ngezantsi.

1. Ukulungiselela iSampuli

Umxube wamanzi nesanti kufuneka ulungiswe ngokuchanekileyo ngaphambi kokuba ufakwe kwi-centrifugation. Inyathelo lokuqala kukufumana isampulu exutywe kakuhle, ukuqinisekisa ukuba isanti isasazwa ngokulinganayo kuwo wonke amanzi.

2. Ukukhetha iCentrifuge

Ukukhetha i-centrifuge efanelekileyo kubalulekile ukuze kufezekiswe ukwahlukana okusebenzayo. I-centrifuge kufuneka ibe namandla okuphatha umthamo wesampulu ngelixa inika amandla aneleyo okujikeleza ukutyhala amasuntswana esanti ukuya eludongeni lombhobho we-centrifuge okanye isitya.

3. Iiparameter zeCentrifugation

Ukuchonga iiparameter ezifanelekileyo ze-centrifugation kubalulekile. Izinto ezifana nesantya se-centrifuge (ukujikeleza ngomzuzu, okanye i-rpm) kunye nexesha zidlala indima ebalulekileyo ekwahlukaniseni amanzi nesanti ngokufanelekileyo. Uvavanyo lunokufuneka ukuze kuphuculwe iimeko zomxube ngamnye othile.

4. Inkqubo yokucoca i-Centrifugation

Nje ukuba iiparameter ezifanelekileyo zichaziwe, umxube kufuneka ubekwe ngononophelo kwiityhubhu ze-centrifuge okanye kwiikhonteyina ezifanelekileyo. Ukubeka iityhubhu kwi-engile ngaphakathi kwe-centrifuge rotor kunokunceda ekwahlukaniseni amanzi nesanti ngokufanelekileyo.

5. Uhlalutyo lweziphumo

Emva kokucoca, hlola iileya ezahluliweyo kwityhubhu okanye kwisikhongozeli. Ukuba iphumelele, iinxalenye zesanti ziya kuxinana ngokufanelekileyo ziye kumphetho ongaphandle ngelixa amanzi ehlala kufutshane nombindi. Susa ngononophelo umaleko wesanti uze uqokelele amanzi aseleyo, ugqibezele inkqubo yokwahlulahlula.

Isiphelo

I-Centrifugation ngokwenene yindlela exabisekileyo yokwahlula amanzi nesanti. Ngokusebenzisa amandla e-centrifugal aveliswa ngexesha lokujikeleza ngesantya esiphezulu, kunokwenzeka ukwahlula ezi zinto zimbini ngokusekelwe kumahluko wazo woxinano. Nangona kukho imingeni ngenxa yoxinano olukhulu lwesanti, ukukhetha i-centrifuge efanelekileyo kunye nokwenza ngcono iiparameter ze-centrifugation kunokoyisa ngempumelelo le miqobo. Uvavanyo olongezelelweyo lunokukhokelela kwiindlela eziphuculweyo zokwenza lula inkqubo yokwahlulahlula.
