摘要：

Simple spectroanalytical methods are proposed for the determination of five heterocyclic nitrogenous compounds. The suggested methods depend upon the formation of the ion-pair complexes of the studied compounds with ammonium reineckate followed by colorimetric and atomic absorption measurement of the complexes solutions. The proposed methods were applied to the determination of some pharmaceutical dosage forms containing the studied compounds. Results obtained were in agreement with those obtained by official and compendium methods.
