Abstract

A simple and sensitive method was investigated for the continuous and simultaneous determination of inorganic anions (SO₄^2-, Cl^-, NO₃^-, F^-) and cations (Na⁺, NH₄⁺, K⁺, Mg²⁺, Ca²⁺) in rainwater over a period of 18 h. A solution of 5 X 10^-3 mol L^-1 DL-malic acid-5% methanol-water was used as the eluent. Good simultaneous separation of anions and cations based on an ion-exclusion mechanism and a cation-exchange mechanism was achieved within 30 min with conductimetric detection. The method was successfully applied to rainwater detection, and proved to be a very useful method for real-time rainwater analysis.
