We present a new type of nanoporous hydroquinone/catechol formaldehyde resin synthesized by a one-pot route, with a surface area of up to 1 112 m(2) . g(-1). The resins show highly efficient reactive adsorption for silver/gold (silver adsorbance up to 2.43 g . g(-1)) and excellent selectivity for gold (K-d is as high as 1 914090 mL . g(-1)). The first-used resins can be regenerated with NaHSO3, and the gold capacities of the recycled PCFR and PHFR reach 44 and 78% of their first loading capacities, respectively.
