N. Flores-Alamo, M. J. Solache-Ríos, R. M. Gómez-Espinosa, B. García-Gaitán
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.
