Iimfuno ze-reagent kunye nokumelwa okusisiseko koxinzelelo lwesisombululo.

Amanzi asetyenzisiweyo kwindlela yovavanyo aya kubhekisa kumanzi adiyiweyo okanye adiyiniweyo ukuba akukho mfuneko ichaziweyo. Xa i-solvent yesisombululo ingachazwanga, ibhekisela kwisisombululo esimanzi. Xa i-concentration ethile ye-H2SO4, i-HNO3, i-HCL kunye ne-NH3 · H2O ingachazwanga kwindlela yokuvavanya, zonke zibhekisela kugxininiso lweenkcukacha ze-reagent ezithengiswayo. Ukuhla kolwelo kubhekiselele kumyinge wethontsi lamanzi adiliweyo aqukuqela ukusuka kwidropha eqhelekileyo, elingana ne-1.0mL ku-20 ° C.

Ukugxininiswa kwesisombululo kunokubonakaliswa ngolu hlobo lulandelayo:
â Ukuya kuxinaniso olusemgangathweni (oko kukuthi, uxinaniso lwento) : luchazwa njengobungakanani bento equlathe i-solute kumthamo weyunithi yesisombululo, iyunithi yi-Mol/L

â¡ Ngokomlinganiselo woxinaniso: oko kukuthi, kubuninzi obuqinileyo obuxutyiweyo bereanti okanye ireyinti yolwelo exutyiweyo inombolo yevolumu, ingabhalwa njenge (1 1) (4 2 1) kunye nezinye iimo.

â¢ Kubunzima (umthamo) iqhezu: kwi-solute kubalwe iqhezu lobunzima okanye iqhezu levolyum yenkcazo yesisombululo, inokuchazwa njengow okanye Phi.

(4) Ukuba i-concentration yesisombululo ibonakaliswe kwiiyunithi zobunzima kunye nomthamo, inokubonakaliswa njenge-g / L okanye ngokuphindaphindiweyo kwayo okufanelekileyo (njenge-mg / mL).

Iimfuno kunye nezinye iimfuno zokulungiselela isisombululo:
Ukucoceka kwee-reagents kunye ne-solvents ezisetyenziselwa ukulungiswa kwesisombululo kufuneka zihlangabezane neemfuno zento yokuhlalutya. Ama-reagents aqhelekileyo agcinwe kwiibhotile zeglasi ezinzima, i-lye kunye nezisombululo zetsimbi zigcinwe kwiibhotile ze-polyethylene, kunye ne-photoproof reagents zigcinwe kwiibhotile ezimdaka.

Iimvavanyo ezinxuseneyo kufuneka zenziwe xa kuhlolwa. Ukubonakaliswa kweziphumo zokuhlola kufuneka kuhambelane nokumelwa kwemigangatho yokucoceka kokutya, kwaye ukubala kunye nexabiso ledatha kufuneka lilandele umthetho wamanani abalulekileyo kunye nomgaqo wokukhethwa kwenombolo.

Inkqubo yokuhlola iya kuqhutywa ngokungqongqo ngokuhambelana namanyathelo okuhlalutya achazwe kumgangatho, kwaye amanyathelo okukhusela aya kuthathwa kwizinto ezingakhuselekanga (ityhefu, ukuqhuma, ukubola, ukutshisa, njl.) Kuvavanyo. Ilabhoratri yokuhlola umzimba kunye neekhemikhali isebenzisa ulawulo lomgangatho wokuhlalutya. Ngokusekelwe ekusekweni kweenkcukacha ezilungileyo zobugcisa, indlela yokumisela kufuneka ibe nemida yokufumanisa, ukuchaneka, ukuchaneka, ukuzoba idatha ye-curve esemgangathweni kunye nezinye iiparitha zobugcisa. Abahloli kufuneka bagcwalise iirekhodi zokuhlola.

Ngaphambili:Kutheni le nto inkcubeko yeeseli idibanisa iiseli ezibomvu zegazi kuqala?
