Abstract EN
The transport of As (III) via supported liquid membrane containing tri-n-dodecylamine (TDDA) as carrier in acidic medium has been studied.
Various factors affecting the transport of As (III) were evaluated.
The effects of acid concentration (HCl), metal ion concentration, carrier, and strippant (NaOH) concentration on transport of As (III) were thoroughly examined.
Mathematical transport model was presented considering the formation of complex between TDDA, acid, and As (III) at feed membrane interface, then the diffusion of this complex through membrane, and finally dissociation of the complex in basic medium at strip membrane interface.
The predicted results of this model strongly agree with experimental ones.
The stoichiometry of complex was determined on the basis of slope analysis of plots.
The mechanism of transport was determined by coupled co-ion transport mechanism, with H+ and Cl− coupled ions.
The optimized SLM was efficiently used for transport of As (III) from acidic feed solution into basic strippant NaOH and oxidized to less toxic form As (V) by adding H2O2.
