Modified cotton fabric for solid-phase extraction and fabrication method

摘要

A method for solid-phase extraction is disclosed. The method includes fabricating a solid-phase extraction medium by incorporating a plurality of modified mesoporous silica particles within pores of a cotton fabric matrix, putting the solid-phase extraction medium in contact with a fluid containing metal ions including one of immersing the solid-phase extraction medium in the fluid containing metal ions or passing the fluid containing metal ions through the solid-phase extraction medium by continuously circulating the fluid through the solid-phase extraction medium, and extracting the metal ions from the fluid by adsorbing the metal ions onto the solid-phase extraction medium responsive to a contact between the solid-phase extraction medium and the fluid containing metal ions.
