Abstract
Single column anion chromatography by indirect UV detection was applied to the determination of 7 common anions(<TEX>$H_2PO_4^-$</TEX>, <TEX>$Cl^-$</TEX>, <TEX>$NO_2^-$</TEX>, <TEX>$NO_3^-$</TEX>, <TEX>$I^-$</TEX>, <TEX>$SO_4^{2-}$</TEX>, <TEX>$SCN^-$</TEX>). A low capacity silica-based anion-exchange column(TSK guardgel QAE-SW; ca. 0.3 meq./g; 4.6 mm i.d<TEX>${\times}$</TEX>150 mm) was used. In separating common anions, we compared naphthalene trisulfonic acid(NTS) and naphthalene disulfonic acid(NDS) to find more sensitive, selective and rapid separation method. And cations and anions can be separated simultaneously in 0.20 mM NTS-5% acetonitrile-water.
