Na intenção de reduzir nutrientes e microrganismos das águas de rio, foi estudado um processo alternativo de tratamento, como o sistema construído de áreas alagadas (CWs), em escala de laboratório. Os parâmetros analisados ...
On-line redox speciation analysis of antimony using L-proline immobilized on controlled pore glass and hydride generation inductively coupled plasma optical emission spectrometry for detection
(Analytica Chimica Acta, 2008-09-12) [Artigo]
L-proline was immobilized on controlled pore glass to study the ability of this material for the separation and preconcentration of Sb(III) and Sb(V). The substrate was packed in a minicolumn and incorporated in a flow ...
