Heavy metal and rock : Humic acid (HA) in natural clays can play an important role in the (im)mobilization (complexation) of toxic metal ions such as radionuclides in the deep geological disposal of high‐level radioactive waste. To better understand the influencing factors, the sorption behavior of Eu 3+ and Gd 3+ ions, as homologues of the actinides Am and Cm, was studied under various conditions.
