Barbora Hudcová et al. recently published a paper focused on metal(loid) removal from aqueous solutions using LDHs (layered double hydroxides) and mixed oxides (thermally treated LDHs; CLDHs). The study addresses the importance of sorbent stability and remediation potential both in water and in real contaminated soils. A complex investigations combining chemistry, solid state analyses and geochemical modeling showed the stabilizing efficiency of Mg-Fe LDHs and CLDHs at different conditions including the dependence on time, pH and the concentrations of metal(loid)s.
