Adsorption of Zinc from sulfate or chloride solutions onto aluminium hydroxide was investigated. The interaction between anion and cation was evaluated by simultaneously fitting the adsorption data according to the Bowden model. The strongest Zinc‐surface interaction, evidenced by the affinity term (K value), was observed in presence of sulfate. That was interpreted as a result of the enhanced chemical affinity of the surface for the cation due to the adsorption of the anion.
