Abstract
Single drop micro extraction (SDME) in combination with electrothermal atomic absorption
spectrometry has been used to preconcentrate and determine thallium (III) ions followed by
speciation ...
Studies on the macrocycle mediated transport in a bulk liquid membrane system of transition metal cations
سال: 2011
خلاصه:
A series of competitive metal ion transport experiments have been performed. Each involved transport from an aqueous source phase across an organic membrane phase into an aqueous receiving phase. The source phase consisted ...
