DISPERSIVE LIQUID-LIQUID MICROEXTRACTION OF NICKEL PRIOR TO ITS

open access: yes, 2014
A sensitive and simple method for the determination of trace nickel was developed by the combination of dispersive liquid-liquid microextraction (DLLME) and microsample injection system-flame atomic absorption spectrometry (MIS-FAAS). Trace nickel was preconcentrated as the 8-hydroxyquinoline chelate by DLLME, and the conditions were optimized by a ...
