Abstract
Two different dye samples Fast Green and Black T were subjected for extracting their ions using a novel methodology based on microfluidics using a membrane without Treatment and membrane coated with copper nanoparticles, which exploits the advantages of miniaturization for sample introduction and extraction of a range of ions through a membrane before and after treatment. The membrane coated with Cu nanoparticles increases the extracting efficiency to 96.3 and 91.62 for Fastgreen membrane and Black T membrane respectively. This due to the new and good physical properties of the membrane surface after coating with nanoparticles.
