1. Pre-concentration by electrostacking and by cloud point for determination of metallic ions in environmental and biological samples / Pre-concentração por electrostacking e por ponto nuvem para determinação de arsenio e cadmio em amostras ambientais e biologicas
The propose of this work is to study two pre-concentration systems for the determination of metallic ions by flame atomic absorption spectrometry (FAAS) and electrothermal atomic absorption speetrometry (ETAAS). First, the use of the bi-directional electrostacking system (BDES) for the pre-concentration and speciation of As(V) and total As in water samples e
