Solid-phase extraction and preconcentration of copper in mineral waters with 4-(2-pyridyl-azo) resorcinol-loaded amberlite XAD-7 and flame atomic absorption spectrometry
A simple, sensitive, accurate, and selective method for determination of ultratrace levels of copper is modified. The method is based on preconcentration of copper on the 4-(2-pyridyl-azo) resorcinol-loaded amberlite XAD-7 (non-ionic copoly[styrene-acrylic compound]) at pH 5.0 to 6.5 for contact tim...
