摘要：

Extraction of strong mineral acids (HCl and H2SO4) from aqueous solutions was carried out using the secondary amine Amberlite LA-2. Experimental measurements were performed with aqueous solutions in the concentration range 0.01-0.5 m. The organic phase comprised 0.5 m Amberlite in diluent toluene. Experimental results were modeled to determine the Nernst distribution coefficients of the two acids and the infinite dilution selectivity. The affinity for H2SO4 is found to be greater than that for HCl.
