ResumoA non-polar stationary phase (PRP-1) modified with cetrimide was used for the high-performance liquid chromatographic separation of anions. The retention behaviour of common anions (F−, C−, NO2−, Br−, NO32− , SO42− and HPO42−) and some weakly dissociated anions (H2AsO3−, HAs042−, H2BO34−, HS−, HCO3− and CO32− was studied using aqueous eluents containing 24% (v/v) methanol, potassium hydrogenphthalate (suitable for indirect UV detection) and tris(hydroxymethyl)aminomethane (pH > 7).
