## Abstract A simple and fast method for the extraction and determination of ppt level of Pb^2+^ and Cu^2+^ ions using octadecylβbonded silica membrane disks modified by a new tetradentates Schiff's base [Bis(2, 4βdimethoxy benzaldehyde) ethylen diimine](TDSB) and inductively coupled plasma atomic
A simple and fast method for extraction and determination of trace amounts of lead(II) ions using octadecyl-bonded silica membrane disks modified with 1,8-dihydroxy-2,7-bis(prop-1Π-enyl)-9,10anthraquinone and atomic absorption spectrometry (AAS) is introduced. Extraction efficiency and the influence
