Simultaneous determination of trifluoroacetate,tetrafluoroborate and halide ions in ionic liquid by ion chromatography
离子色谱法同时测定离子液体中的三氟乙酸根、氟硼酸根及卤素离子

A method was developed for the simultaneous determination of trifluoroacetate,tetrafluoroborate and halide ions (F-,Cl-,Br-) by ion chromatography with direct conductivity detection.The chromatographic separation was performed on a Shim-pack IC-A3 anion-exchange column with potassium biphthalate,phthalic acid+tris(hydroxymethyl)-aminomethane,and p-hydroxybenzoic acid+tris(hydroxymethyl)-aminomethane+boric acid as eluent,separately.The effects of the nature of eluent,eluent concentration,acetonitrile concent...
