Preconcentration and separation of nickel, copper and cobalt
DOI: 10.1016/J.JHAZMAT.2006.12.070 Corpus ID: 34643239; Preconcentration and separation of nickel, copper and cobalt using solid phase extraction and their determination in some real samples.A thermally reversible gel was utilized as a separation matrix while in its solid state (30 °C). This thermal gel provided sufficient separation resolution to identify three variants of a fluorescently-labeled model protein. To increase detection sensitivity, analyte preconcentration was conducted in parallel with the separation.Simultaneous Preconcentration and Separation of Native Protein

Chelating agent-free solid phase extraction (CAF-SPE) of uranium
Therefore, preconcentration or separation of trace elements from matrices is necessary to improve their detection and sensitivity by FAAS . Solid phase extraction has risen to the forefront methods for the removal of heavy metals due to minimal solvent consumption, flexibility, absence of emulsion [ 9 ], high concentration factor and A fast method for separation of iron, nickel, lead, and zinc from water matrices prior to their atomic absorption spectrometry (AAS) is described. The separation and preconcentration of metals was performed by precipitate colloid flotation with cobalt(III) hexamethylenedithiocarbamate, Co(HMDTC)3, as a new collector.Cobalt(III) Hexamethylenedithiocarbamate as a New Collector
