A nanoporous reactive adsorbent incorporates a relatively small number of relatively larger reactant, e.g., metal, enzyme, etc., particles ( 10 ) forming a discontinuous or continuous phase interspersed among and surrounded by a continuous phase of smaller adsorbent particles ( 12 ) and connected interstitial pores ( 14 ) therebetween. The reactive adsorbent can effectively remove inorganic or organic impurities in a liquid by causing the liquid to flow through the adsorbent. For example, silver ions may be adsorbed by the adsorbent particles ( 12 ) and reduced to metallic silver by reducing metal, such as irons, as the reactant particles ( 10 ). The column can be regenerated by backwashing with the liquid effluent containing, for example, acetic acid.
