Semi-interpenetrating hybrid membranes containing ADOGEN® 364 for Cd(II) transport from HCl media

- Semi-interpenetrating hybrid membranes are used for quantitative cadmium(II) recovery.
- Optimization of membrane and solutions compositions is performed.
- Membranes present increased stability respect to polymer inclusion membranes.
- Models for cadmium (II) extraction and transport are proposed.
- Excellent selectivity for Cd(II) over Ni(II), Cu(II) and Pb(II) was achieved.
