Izidingo ze-reagent kanye nokumelwa okuyisisekelo kokugxila kwesixazululo.

2022-12-23

Amanzi asetshenziswe endleleni yokuhlola azobhekisela emanzini acwengekile noma amanzi akhishiwe uma zingekho ezinye izidingo ezibonisiwe. Uma i-solvent yesisombululo ingacacisiwe, ibhekisela kusixazululo esinamanzi. Uma ukugxiliswa okuqondile kwe-H2SO4, HNO3, HCL ne-NH3·H2O kungacacisiwe endleleni yokuhlola, konke kubhekisela ekugxiliseni kokucaciswa kwe-reagent etholakalayo kwezohwebo. Ukwehla koketshezi kubhekisela enanini lethonsi lamanzi acwengekile eligeleza lisuka ku-dropper evamile, elilingana no-1.0mL ku-20 ° C.

Ukugxila kwesixazululo kungavezwa ngezindlela ezilandelayo:
â Ekuhlanganiseni okujwayelekile (okungukuthi, ukuhlangana kwento) : kuchazwa njengenani lento equkethe i-solute kuvolumu yeyunithi yesisombululo, iyunithi ithi Mol/L

â¡ Ngokulingana nokugxilisa ingqondo: okungukuthi, kumthamo wevolumu exubile ye-reagent eqinile noma inombolo yevolumu exutshiwe, ingabhalwa ngokuthi (1 1) (4 2 1) nezinye izinhlobo.

â¢ Kwingxenye yesisindo (ivolumu): ku-solute kubalwe ingxenye enkulu noma ingxenyenamba yevolumu yokuvezwa kwesixazululo, ingachazwa ngokuthi w noma Phi.

(4) Uma ukugxila kwesixazululo kuvezwa ngamayunithi wesisindo nomthamo, kungavezwa njenge-g/L noma ngokuphindaphinda kwakho okufanele (okufana no-mg/mL).

Izidingo kanye nezinye izidingo zokulungiswa kwesixazululo:
Ukuhlanzeka kwama-reagents kanye ne-solvents esetshenziselwa ukulungiswa kwesixazululo kufanele kuhlangabezane nezidingo zento yokuhlaziya. Ama-general reagents agcinwa emabhodleleni engilazi aqinile, i-lye nezixazululo zensimbi zigcinwa emabhodleleni e-polyethylene, futhi ama-photoproof reagent agcinwa emabhodleleni ansundu.

Ukuhlolwa okufanayo kufanele kwenziwe ekuhlolweni. Ukumelwa kwemiphumela yokuhlolwa kufanele kuhambisane nokumelelwa kwezindinganiso zokuhlanzeka kokudla, futhi ukubalwa kanye nenani ledatha kufanele kulandele umthetho wezinombolo ezibalulekile kanye nomthetho wokukhethwa kwenombolo.

Inqubo yokuhlola izoqhutshwa ngokuhambisana ngokuqinile nezinyathelo zokuhlaziya ezichazwe ezingeni, futhi izinyathelo zokuzivikela zizothathwa ngokumelene nezinto ezingaphephile (ubuthi, ukuqhuma, ukugqwala, ukushisa, njll) ekuhlolweni. Ilabhorethri yokuhlola ngokomzimba namakhemikhali isebenzisa ukulawulwa kwekhwalithi yokuhlaziya. Ngokusekelwe ekusungulweni kokucaciswa okuhle kobuchwepheshe, indlela yokunquma kufanele ibe nemikhawulo yokuthola, ukunemba, ukunemba, ukudweba idatha yejika elijwayelekile neminye imingcele yobuchwepheshe. Abahloli kufanele bagcwalise amarekhodi okuhlola.
