A flow-injection on-line system was developed for the trace determination of cobalt by flame atomic absorption spectrometry (FAAS) with separation and preconcentration on a minicolumn packed with a poly(aminophosphonic acid) chelating resin (PAPhA). This resin allows the selective separation of coba
An automated robotic method for sample pretreatment was developed for copper determination in environmental and biological materials at the low microgram per gram level. The robotic station performing the preliminary operations as weighing of sample and acid digestion was coupled with the flowinject
## Abstract A new simple and reliable method has been developed to separate and preconcentrate trace copper ion in drinking water and tea samples for subsequent measurement by flame atomic absorption spectrometry (FAAS). The copper ions are adsorbed quantitatively during passage of aqueous solution
Solid phase extraction using sodium diethyldithiocarbamate (DDC) loaded on silica gel has been used for preconcentration of trace amounts of copper from commercial mineral waters prior to its determination by flame atomic absorption spectrometry. The sorption and releasing of copper have been studie
