Abstract

Membranes due to their main advantages in separation, including low energy consumption, high precision, high separation yield and no chemical materials release got considerable attentions. Producing membranes with low fouling and longer life time with high accuracy in separation is very important. One of the most useful methods in improving operational conditions of membranes is deposition of nano materials and nano layers on the surface or in the polymeric matrix of the membrane based on nano biotechnology methods. In this research, poysulfone membranes were modified in four methods with polymerization of polyrhodanine and were used to remove phenol from aqous solutions. Rhodanine and its derivatives were used as anti bacterial, anti virus, anti histamic, anti convulsant and anti diabetic materials in biological activities. This material is a selective inhibitor for replication of viruses such as HIV-1 and Echovirus type12. Modified membarnes showed different permeation and separation behaviors. In this research maximum phenol separation for modified membrane type (1) was more than 93%. Studies showed that modification of polysulfone membrane with polrhodanine leads to antifouling properties improvement and increase the adsorbed amount of phenol in modified membranes.
