摘      要：Gold is a unique element,characterized not only by limited,though still reasonable,availability (useful for monetary applications) but also for its rather unique properties useful for many industries [1]:chemical inertness,high electrical conductivity,plasticity,*** gold reserves in Earth’s crust diminish with traditional minings’urban mining’that recycles gold from gold-containing wastes (such as electronic waste,e-waste) has emerged as an important supply method for gold sustainability [2].One critical step in such a recycling process is the use of an adsorbent to extract gold from e-waste leachate that contains complex metal ***,the gold adsorbent should have a high extraction capacity,selectivity and,importantly,economic *** many porous materials have been developed for gold extraction from e-waste [3-6],materials that show high gold extraction capacity with precise gold selectivity to ppm or even lower concentrations are highly required.
