EDTA modified layered double hydroxides (LDHs) were investigated as potential sorbents to remediate heavy metals pollution. The polidentate ligand was introduced by an exchange method in a Zn-Al-LDH, which takes place with partial erosion of the layers, causing the intercalation of [Zn(EDTA)](2-) complex instead of the ligand. [Cu(H(2)O)(6)](2+) cation was selected as a model cation to study the uptake mechanism, exploring the elimination kinetics from the first minutes up to the steady state… CONTINUE READING
