Ngokushintshwa kwe-asidi ebilayo ephansi nge-asidi ebilayo ephezulu, i-F - ne-Cl - ihlanganiswa ne-sulfuric acid njenge-distillation ejenti ekushiseni okuthile kokuhlukaniswa nokunothisa.Kusetshenziswa i-CIC-D120 ion chromatograph , SH-AC-3 amakholomu anion.3.6 mM Na2CO3+4.5 mM NaHCO3 eluent kanye ne-bipolar pulse conductance method,ngaphansi kwezimo ezinconyiwe zechromatographic, i-chromatogram imi kanje.
Imikhawulo yokuthola ye-F- ne-Cl- ingu-0.84ug/L no-0.37 ug/L.Ukutholwa kwe-F- ne-Cl- kungu-91%-107% no-95%-105%(n=10).Ama-ion akhona kusixazululo sokucwenga awazange abe nokuphazamiseka ekunqumeni kwe-F- kanye ne-Cl-.
