PHENOL REMOVAL BY SUPPORTED LIQUID MEMBRANES

This paper examines the application of the supported liquid membrane ( SLM) to phenol removal. n-Decanol was proven to be a suitable membrane liquid. The phenol transfer kinetics through the SLMs is quantitative ly estimated according to models based on the resistance-in-series con cept. The models can be modified to describe the performance of decaye d SLMs and thereby provide insight into the effect of membrane liquid loss and penetration of aqueous solutions on the phenol flux. An exper imental method is described for the measurement of mass transfer coeff icients in the bulk phases using the well-characterized Anopore membra ne.
