Abstract

We have studied the possibility of using zinc–aluminum layered double hydroxide intercalated hexacyanoferrate (II)-ions for sorption removal of Cu(II), Co(II) and Pb(II) from aqueous solutions. The article showed high efficiency of a sorbent for removal from aqueous solutions of Cu(II) and P(II). It was found that a model of kinetics of the pseudosecond order the most precisely describes the sorption process of studied ions of heavy metals (R² > 0.99).
