TLDR
An online column preconcentration technique for flow-injection atomic absorption spectrometry was developed in this paper, where diverse metal ions (Cd2+, Zn2+, Cu2+, Mn2+, Pb2+, Fe3+ and Cr3+) in solution were concentrated quantitatively by a microcolumn (7-mm × 4-mm id) packed with Muromac A-1, which is an iminodiacetate chelate resin, in a flowinjection system from the pH dependence of the uptake of the ions, all the divalentAbout:
