摘要

Abstract

A novel constant interfacial area cell (NCIAC)

by spatially separating the agitation from liquid flow circulation of organic and aqueous two phases

was suggested to obtain detailed kinetic data for Er(Ⅲ) extraction from chloride medium by 2-ethyl-hexyl-phosphonic acid mono-(2-ethylhexyl) ester (EHEHPA). Different from the traditional Lewis cell and the constant interfacial area cell with laminar flow

the concentrations of Er(Ⅲ) in organic and aqueous two phases were uniform

and the stability of the interfacial area between the two phases could be controlled effectively. Therefore

the special requirements for the design of agitators in the traditional Lewis cell and the constant interfacial area cell for minimizing the influence of diffusion resistance could be avoided. Experimental results indicated that the extraction kinetics was mainly affected by the aqueous flow rate

interfacial area between organic and aqueous two phases

and the aqueous pH values. An extraction kinetic equation was suggested based on the experimental data.
