Abstract:

A chitosan ultrafiltrating membrane was pr epar ed by phase reverse technique involv ing coagulatio n of the chitosan sloution in NaOH solution. The membrane prepared by the technology has ex cellent separation performance for such an acid r ed B dye which was hard of treatment by common coagulation technology.The decolorization efficiency of acid red B aqueous solution achieved 91%~ 98%. To real printing and dy eing waste water, the decolorization efficiency was above 95% and the removal of COD was 88%. Its effect w as better than that of tranditio nal treatment methods.

Key words: chitosan ultrafiltrating membrane, co agula-tion bath, printing and dyeing wastewater
