Tom qab ultrasonic extraction thiab centrifuge sib cais thiab nag lossis daus, hlau ore kuaj tau lim los ntawm IC-RP kem, IC-Na kem thiab 0.22 um microporous filtration membrane feem.Siv CIC-D120 ion chromatograph, SH-AC-3 anion kem, 3.6 mM Na2CO3 + 4.5 mM NaHCO3 eluent thiab bipolar pulse conductance txoj kev, raws li kev pom zoo chromatographic tej yam kev mob, chromatogram yog raws li nram no.
Qhov kev kuaj pom ntawm F- thiab Cl- yog 2.1 ug / g thiab 3.5 ug / g.Kev rov qab los ntawm F- thiab Cl- yog 96% -104%.Nws tuaj yeem siv rau kev tsom xam ntawm ntuj hlau ore, hlau ore concentrate thiab lwm yam qauv.
