Interaction mechanism of Eu(III) on magnetic biochar(MB) was investigated by batch, XPS, EXAFS and modeling techniques. Maximum Eu(III) adsorption capacity on MB is 105.53 mg/g at pH 3.0, which was demonstrated to various functional groups by XPS analysis. No effect of ionic strength revealed inner-sphere surface complexation. According to EXAFS analysis, inner-sphere surface complexation and surface co-precipitation dominated the Eu(III) adsorption at low and high pH, respectively. Eu(III) adsorption can be simulated by surface complexation modeling. These results indicated that MB can be used a promising candidate for the highly effective adsorbent of radionuclides.
