Removal of lead from aqueous solution using synthetic hydrotalcite / Sharinah Ideris
Layered Double Hydroxides (LDHs) were found to have high anionic exchange capacity as removal metal cations contaminants from aqueous solution. In this study, MgAl-CO3 was synthesized by using co precipitation method. Different parameters that affect the adsorption processes were studied which inclu...
