An on-line preconcentration procedure for the determination of heavy metal ions using Flowinjection approach with flame atomic absorption spectroscopy is developed significantly in recent years. This review focuses on chelating resins based on Amberlite XAD resins which have been used in Flow Injection analysis since 1996.The factors like detection limit, enrichment factor and sample throughput are reported. Chelates immobilized on Amberlite XAD matrices and the metal ions separated and determined together with references are given in the review.
