Abstract

The adsorption of soluble Sn(TV) species on goethite (FeOOH), a naturally occurring mineral, was investigated in 0.01 M NaCl solution at ambient temperature. The sequential spike method was used to obtain the distribution coefficient (Kd). Kd values of higher than 1×107 ml/g at neutral pH, and 3×105 ml/g at pH 11 were obtained. It is observed that Kd values decrease with increasing pH. In the desorption experiment, the sequential extraction method was applied. The extractants such as 0.1 M NaOH, Tamm's acid oxalate and Coffin's reagent were used. The result indicates that the adsorption consists of both reversible and irreversible reactions, and that the most of fractions in adsorption of Sn on goethite correspond to the irreversible adsorption or a stable fixation. Moreover, it is suggested that the reversible adsorption converts to the irreversible adsorption with time.
