Hybrid materials based on clays and polyamines are supposed to be efficient heavy metals sorbents due to the well-known adsorption behaviour of the clay matrix and to the coordination properties of un-protonated amino groups. For this purpose, a montmorillonite clay was modified with three different aliphatic polyamines: L6 and L10 have a...

Uptake and release capability of a new organoclay material were assessed with the final goal to evaluate its applicability in recovering REs from solutions. Capture and release capability have been tested towards a La ions model solution, and interaction mechanism and reactions, active in both capture and release processes, were related to the...

In this work, Ca-montmorillonite (STx), natural and modified (STx-L6) with a linear penta-ethylene-hexamine (L6), were tested as sorbents in a liquid/solid process for La and Cu capture in bionic model solutions. Twelve La/Cu ratios in solution were set and analyzed with the final target of investigating the capture mechanisms when both Cu and...
