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
## An on-line column preconcentration technique for flow-injection flame atomic absorption spectrometry has been developed for the determination of trace metals in natural waters. A minicolumn (20 mm X 2 mm id.) filled with a poly(aminophosphonic acid) chelating resin (PAPhA, 20-30 mesh) was used
