A simple separation/preconcentration method for the determination of aluminum in drinking water and biological sample

► An efficient separation/enrichment of Al3+ method to overcome the problem of high matrix species. ► Prior separation of matrix cations, no interference study was required for this proposed method. ► The fluorescence intensity of morin-Al3+ complex was analyzed by spectrofluorimetry. ► The developed method is a cost effective technique prior to subjecting processing or desalination.
