Activated carbon adsorption is a promising technique for treatment of low-concentration heavy metal pollutants with high efficiency, simple operation, and flexibility;however, the cost of commercial activated carbon is too high. Therefore, much attention has been paid to activated carbon derived from low-cost agricultural and forest wastes. In this work, adsorption of Cd and Pb in aqueous solutions were conducted through batch experiments using Typha angustifolia carbon (TC) and Salix matsudana carbon (SC) prepared by phosphoric acid activation, and the adsorbents were characterized using SEM,...
