Raws li kev hloov cov kua qaub qis los ntawm cov kua qaub siab kub, F - thiab Cl - yog distilled ua ke nrog sulfuric acid ua distillation tus neeg sawv cev ntawm ib qho kub rau kev sib cais thiab enrichment.Siv CIC-D120 ion chromatograph, SH-AC-3 anion txhua.3.6 mM Na2CO3 + 4.5 mM NaHCO3 eluent thiab bipolar pulse conductance txoj kev, raws li cov kev pom zoo chromatographic, cov chromatogram yog raws li nram no.
Qhov kev kuaj pom ntawm F- thiab Cl- yog 0.84ug / L thiab 0.37 ug / L.Kev rov qab los ntawm F- thiab Cl- yog 91% -107% thiab 95% -105% (n = 10).Lub coexisting ions nyob rau hauv cov tshuaj plating tsis muaj kev cuam tshuam nrog kev txiav txim ntawm F- thiab Cl-.
