Abstract

The synthesis of sorption materials for retention and/or preconcentration of species of clinical and environmental interest, such as metal ions, is an important area of contemporary research. We report herein the synthesis of different solid supports of anthracene-phosphine sulfide for Cu(II) and Pb(II) preconcentration. Sensing properties of these materials were also evaluated using a flow-through optosensing approach.

Keywords: solid phase synthesis, metal sorbents, fluorescence sensing, continuous monitoring

 

Resumo

А síntese de materiais para retenção e/ou pré-concentração de espécies de interesse clínico e ambiental, como íons metálicos, constitui uma importante área de pesquisa atual. Neste trabalho, descrevemos a síntese de diferentes suportes sólidos de antraceno - sulfeto de fosfina para pré-concentração de Cu(II) e Pb(II). As propriedades sensoras destes materiais também foram avaliadas usando a abordagem optosensitiva em fluxo contínuo.
