摘要

Abstract

Phase equilibrium and kinetic experiments of phenol on NKAⅡ resin under ultrasonic field and non-ultrasonic field were separately conducted at normal temperature.The model for estimating diffusion coefficient of phenol on the NKAⅡ resin was established.Results showed that application of ultrasound can change the phase equilibrium state of NKAⅡ/phenol/water system which has reached equilibrium under normal condition.The phase equilibrium state of the system shift towards decrease in the amount adsorbed of phenol on NKAⅡ resin.In addition

acoustic cavitation could make diffusion coefficient of phenol in NKAⅡ resin in ultrasonic field increase by one order of magnitude in comparison with the diffusion coefficient determined in non-ultrasonic field.The diffusion coefficient increased with the increase in acoustic power.However

it was found that if the acoustic intensity was larger than 0.057W·cm -2

slight pulverization of the NKAⅡ resin occurred

which should be avoided in application.
