On-line preconcentration employing a tannin resin for copper determination in plant material and food stuff by atomic absorption spectrometry
A flow system for copper on-line preconcentration, employing a tannin resin prepared from Eucalyptus Saligna Sm, with determination by flame atomic absorption spectrometry is proposed. The manifold was designed by assembling an automatic injector-commutator and a set of three-way solenoid valves whi...
