  • Cu's adsorption the (II)nd and Zn the (II)nd in watery solution in systems monkey and bicomponente.

  • The time of balance for solutions monkey and bicomponente it(he,she) is kept in 6 and 10 hours for Cu the (II)nd and Zn the (II)nd respectively.

  • The model of Langmuir provides the best adjustment of the information of Cu the (II)nd and that of Freundlich for the Zn the (II)nd.

  • The energy of adsorption denotes a mechanism of adsorption for fisisorción for the Zn the (II)nd in solutions monkey and bicomponente.

  • The mechanism of adsorption for the Cu the (II)nd monocomponent comes closer to quimisorción.

  • The order of affinity of the adsorbent for the metallic ions was: Cu the (II)nd>> Zn the (II)nd.
