Method of using a nanoporous membrane for the detection and quantification of heavy metal ions in a fluid by anodic stripping voltammetry

摘要

Method and a device for capturing heavy metal ions included in sewage sludge. The method comprises steps of: a) placing in the fluid a functionalised radio grafted track-etched membrane FRTEM which contains polymer nanopores; this membrane comprising a first electrode on one side of the membrane, b) selectively capturing heavy metal ions inside the polymer nanopores, c) applying an anodic stripping voltammetric ASV analysis on the membrane in order to differentiate and quantify captured metal ions, said first electrode being used as an ASV detection electrode.
