Alginate and algal-biomass (Laminaria digitata) beads were prepared by homogeneous Ca ionotropic gelation. In addition, glutaraldehyde-crosslinked poly (ethyleneimine) (PEI) was incorporated into algal beads. The three sorbents were characterized by scanning electron microscopy (SEM) coupled with energy dispersive X-ray analysis (EDX): the sorption occurs(More)
Metal hexacyanoferrates are very efficient sorbents for the recovery of alkali and base metal ions (including radionuclides such as Cs). Generally produced by the direct reaction of metal salts with potassium hexacyanoferrate (the precursors), they are characterized by ion-exchange and structural properties that make then particularly selective for Cs(I),(More)
Chitosan is naturally bio-polymer obtained through chitin deacetylation. Chitosan can be molded in several shapes, such as membranes, microspheres, gel beads and films, and is able to use for wide application including food and nutrition, cosmetic, pharmaceutical, biomedicai, water treatment and other purposes. The aim of this work was to characterize the(More)
