摘要：

With increasing production and application, carbon nanotubes (CNTs) will enter into the environment in significant masses in upcoming years. CNTs have great potential to disturb the bioavailability and toxicity of other contaminants because of their high and strong adsorption capacity. This study investigated the influence of CNTs on the Cd(II) adsorption behavior by sediment-CNTs mixture at different CNTs/sediments ratios. The results showed that the adsorption kinetic data were well described by the pseudo-second-order model, and the pseudo-second-order rate constant (k
