Abstract
Packing with an alkylamide chemically bonded stationary phase (AP) for high performance liquid chromatography (HPLC) was applied for the determination of inorganic anions in water samples. The conventional octadecyl (C18) stationary phase was used as a reference column packing material for reversed‐phase (RP) HPLC. The mobile phase composition under ion‐pair RP HPLC conditions, was optimized by changing the concentration of the organic modifier (acetonitrile), the ionic strength of eluent (addition of TRIS), and the pH value. The data obtained were used for qualitative and quantitative determination of anions in samples of drinking water and water from the Vistula River.
