Montmorillonite (Mt) has been considered as low-cost and high efficient adsorbent for heavy metal cations, and thermal treatment can be a facile approach for sequestration of the adsorbed heavy metal cations on Mt. This work was intended to study the effects of heating temperature on the sequestration efficiency of Cr on Mt. Toward this aim, thermal treatment of the spent Mt after adsorption of Cr...
Clay minerals are low-cost, high-efficient, and environmentally-friendly adsorbents for heavy metal cations. Proper disposal of the spent clay minerals, however, is still a big challenge holding back their wide applications in environmental remediation. In this work, the spent montmorillonites (Mt) after the adsorption of Cu2+ or Cd2+ were thermally treated, with the aim of in-situ sequestrating the...
