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