Abstract
Extraction rates of zinc with ammonium chloride salts of Amberlite LA-2 in hexane were measured in a horizontal rectangular channel. The experimental results were analyzed by considering the processes of diffusion in both solutions, adsorption and desorption to/from the interface and reactions at the interface for the species related as following steps;(BHCl)2,org + σ = (BHCl)2,ad (1)(BHCl)2,ad + ZnCli,aq–(i–2) = (BH)2ZnCl4,ad + (i – 2)Claq– (2)(BH)2ZnCl4,ad = (BH)2ZnCl4,org + σ (3)(BH)2ZnCl4,org + (BHCI)2,org = (BH)4ZnCl6,org (4)2(BH)2ZnCl4,org = ((BH)2ZnCl4)2,org (5)The extraction rates of zinc was interpreted from the rate equation that the interfacial reaction between (BHCl)2 adsorbed at the interface and zinc chloride in the aqueous solution shown in step (2) is the rate-determining step. Some parameters of the rate equations were estimated.
