The complex technology of molecular imprinting with a photocatalytic reaction introduces novel ways of treating industrial and living sewage. This paper deals with the effects of trace $TiO_{2}$ on $Ag^{+}$-imprinted or non-imprinted adsorbents. $NanoTiO_{2}$ was added during the preparation of the adsorbents. The performance of these adsorbents was compared with other common adsorbents, such as activated carbon and chitosan. $TiO_{2}$ loading improved the adsorption ability for $Ag^{+}$ of adsorbents. Adsorption equilibrium could be rapidly achieved at an initial Ag+ concentration of 200mg/L under different light conditions (UV, visible light, and dark). After $TiO_{2}$ loading, the maximal adsorption capacity of $Ag^{+}$-imprinted and non-imprinted adsorbents was 25.0% higher, at 155.0 and 134.3 mg/g, respectively, at the initial $Ag^{+}$ concentration of 1,000mg/L. In order to understand the binding state of Ag, Ti on the adsorbents surface, FTIR, XPS were measured. The FTIR analysis, before and after adding $TiO_{2}$, indicated that $TiO_{2}$ bound with adsorbents through hydrogen bonding. XPS analysis, before and after adsorption, indicated $Ag^{+}$ was reduced to $Ag^{0}$ on the adsorbent surface, leading to an increased adsorption of $Ag^{+}$.
