Immobilization of Lignite into PVAl Sponges

Immobilization of Lignite into PVAl Sponges

Our work was dedicated to the immobilization of lignite into highly porous hydrophilic sponges made of acetalized PVAl. These sponges were prepared by acidic formalization of aqueous solution of PVAl. Pores were formed by gaseous H2, which originated from the reaction of powder aluminum with acid. Resulting sponges were of open-cell structure, were highly hydrophilic and had variable porosities depending on the amount of blowing agent (aluminum). A set of sponge samples with varying lignite content was prepared and the properties of resulting sponges were studied. We also studied the sorption capacity of lignite-containing sponges on model pollutants (Cu(II) ions).
