A simple, picky and sensitive method has been investigated for concurrently determining anions (Cl −, N0 3 −, SO 4 2−) and cations (Na +, NH 4 +, E +, Mg 2+, Ca 2+) in acid rain and associated environmental marine environments in main Asia. The technique entails simultaneous ion-excIusion-cation-exchange chrómatography with conductimetric recognition on a polyacrylate weakly acidic cation-exchange resin column with a wéak-acid eIuent. With the wéak-acid eluent (tártaric acid) both anions and cations were separated simultaneously, centered on ion-excIusion and cation-éxchange system.

Still to pay to the existence of L + ions in the tartaric acid solution eluent, the detector response was optimistic for the anions and harmful for the cations. Making use of a 5 m M tartaric acidity-7.5% methanol-water eluent, good simultaneous separation and recognition were achieved in about 30 min.

The outcomes indicated an ionic balance of about 100% between the anions (like HCO 3 −) and the cations (including L +). Prior article in issue. Next article in problem.
