Ligandless-dispersive liquid–liquid microextraction of trace amount of copper ions

Analytica Chimica Acta, 2009
In the present work, a new ligandless-dispersive liquid-liquid microextraction (LL-DLLME) method has been developed for preconcentration trace amounts of copper as a prior step to its determination by flame atomic absorption spectrometry. In the proposed approach 1,2-dicholorobenzene and ethanol were used as extraction and dispersive solvents ...
