| Abstract: | A method was developed for the determination of tetrafluoroborate by ion-exclusion chromatography coupled with direct conductivity detection.Chromatographic separation was performed on a Shim-pack SCR-102H column.Influences of eluent and column temperature on retention time of tetrafluoroborate were investigated.The results indicated the retention time of tetrafluoroborate was increased with the increase of column temperature,and the retention process of tetrafluoroborate was endothermic.The optimal chromat... |
