Abstract
Ethylenediamine (en) reacts with salicylaldehyde and beryllium(II) in a weakly basic solution to form a fluorescent beryllium(II)-Schiff base complex. A fluorometric method for the determination of en by using the beryllium(II) complex has been established. Ethylenediamine could be determined in 2×10−7–2×10−5 mol dm−3 within a relative standard deviation of 3%. The detection limit of en was 8×10−9 mol dm−3. Ammonia, diethylamine, and triethylamine does not interfere with the determination of en. The present method has been applied to the analysis of en in aminophylline tablets. The fluorometric method for the determination of trace amount of amino acid by using an aluminum(III)-Schiff base complex has also been investigated.
