Kusanthula chilengedwe

F-, Cl-, NO2-, SO42-, Na+, K+, NH4+, Mg2+, Ca2+, etc. ndi zinthu zofunika kuti zidziwike pophunzira za khalidwe la mumlengalenga ndi mvula.Ion chromatography (IC) ndiye njira yoyenera kwambiri yowunikira zinthu za ayoni.

Mumlengalenga mpweya chitsanzo: Nthawi zambiri ntchito olimba mayamwidwe chubu kapena mayamwidwe madzi kuti sample.For kusanthula sulfure dioxide ndi oxides nayitrogeni, m'pofunika kuwonjezera mlingo woyenera wa H2O2 mu mayamwidwe kapena m'zigawo njira, oxidize SO2 kuti SO42 -, ndiyeno dziwani ndi njira ya IC.

Chitsanzo cha mvula: Pambuyo poyesa, imayenera kusefedwa nthawi yomweyo ndikusungidwa mufiriji pa 4 ℃, ndikuwunikidwa mwamsanga.

Tinthu tating'ono: Zitsanzo zachilengedwe za voliyumu kapena nthawi inayake zidasonkhanitsidwa, ndipo 1/4 ya zitsanzo zomwe zidasonkhanitsidwa zidadulidwa molondola.Zingwe zosefedwa zidadulidwa ndi lumo loyera ndikuyika mu botolo la pulasitiki (polyester PET), madzi opangidwa ndi deionized amawonjezeredwa, amachotsedwa ndi mafunde akupanga, kenako ma voliyumu adakhazikitsidwa ndi botolo la volumetric.Pambuyo Tingafinye amasefedwa kudzera 0.45µm microporous fyuluta nembanemba, ndi izo zikhoza kusanthula; Natural fumbi zitsanzo anatsanuliridwa mu beakers ndi kachulukidwe deionized madzi ndiyeno yotengedwa ndi akupanga yoweyula, amasefedwa ndi kutsimikiziridwa ndi pamwamba njira yomweyo.
