I-F-, Cl-, NO2-, SO42-, Na+, K+, NH4+, Mg2+, Ca2+, njl. zizinto eziyimfuneko eziza kufunyanwa kwisifundo somgangatho we-atmospheric kunye nemvula.Ion chromatography (IC) yeyona ndlela ifanelekileyo yohlalutyo lwezi zinto ze-ionic.
Isampulu yegesi yomoya: Ngokuqhelekileyo sebenzisa ityhubhu yokufunxa eqinileyo okanye ulwelo lokufunxa kwisampulu. Kuba uhlalutyo lwesulfure dioxide kunye nenitrogen oxides, kuyimfuneko ngokubanzi ukongeza isixa esifanelekileyo se-H2O2 kwisisombululo sokufunxa okanye sokutsalwa, oxidize SO2 ukuya kwi-SO42 -, kwaye emva koko. yigqibe ngendlela ye-IC.
Isampulu yemvula: Emva kwesampulu, kufuneka ihluzwe ngokukhawuleza kwaye igcinwe kwifriji kwi-4 ℃, kwaye ihlalutye ngokukhawuleza.
Iisampuli zesuntswana:Iisampulu zokusingqongileyo zomthamo othile okanye ixesha zaqokelelwa, kwaye i-1/4 yesampulu eqokelelweyo yasikwa ngokuchanekileyo.I-membrane ezihluziweyo zinqunywe ngeesikere ezicocekileyo kwaye zifakwe kwibhotile yeplastiki (i-polyester PET), amanzi adibeneyo adityanisiwe, akhutshwe ngamaza e-ultrasonic, emva koko imiqulu yalungiswa ngebhotile ye-volumetric.Emva kokuba isicatshulwa sihluzwe nge-0.45µm ye-microporous filter membrane, inokuhlalutya; Iisampulu zothuli lwendalo zagalelwa kwiibeakers ezinamanzi adiyiniweyo ngokomlinganiselo kwaye zakhutshwa ngamaza e-ultrasonic, ahluzwa kwaye agqitywe ngale ndlela ingasentla.
