摘要：
We have obtained sorbentsfor recovery of heavy metal ions from aqueous solutions by modification of kaolinite and metakaolinite, aluminum oxyhydroxide and aluminum hydroxide by polyphosphates. Using sorption of Ni2-, Co2+, and Cr3+ as an example, we have shown that the sorbents have high sorption capacity and distribution coefficient with respect to heavy metal ions. We have studied the composition of the complexes formed We have developed methods for granulation of the sorbents with a binder and for regeneration of the sorbents. © 1999 Kluwer Academic/Plenum Publishers.
