Abstract
  In this study graphene quantum dots/eggshell membrane nanocomposite (GQDS/ESM) is prepared and used as an efficient solid-phase extraction (SPE) sorbent for preconcentration of organophosphorus pesticides (OPPs) from aqueous solutions. The retained analytes on the sorbent are stripped by acetonitrile ...  Read More
