【Abstract】 With their increased production,application,and emissions to environment,adverse effects of carbon nanotubes(CNTs) on environment and human health have attracted wide attention.However,much of the research effort has been focused on biological effects of CNTs alone.Due to their high adsorption ability,CNTs are easy to adsorb various toxic metal ions in environment and form CNT-metal ions complex.Biological effects of the complex differ from the individual effect of CNTs or ions,being far from a simple pile-up effect of CNTs and ions.In this paper,we give a review on metal ions adsorption on CNTs,the affecting factors,and environmental toxicology of CNT-metal ions complex.We also point out that radionuclide tracer techniques and synchrotron radiation techniques can play important roles in studies on interactions of metal ions with CNTs and the biological effects on environmental toxicology.更多还原
