| Abstract: | A method was developed on a monolithic column for the fast determination of trace iodate(IO-3) by ion-pair chromatography with direct conductivity detection.The analytes were separated using a mobile phase of tetrabutylammonium hydroxide(TBA)-phthalic acid-acetonitrile on a reversed-phase silica-based monolithic column.The effects of eluent,flow rate and column temperature on the retention of iodate were investigated.The optimized chromatographic conditions for the determination of the anion were as follows... |
