Abstract

In this study, a tetramine-substituted calix[4] arene derivative, which was synthesised from calix[4] arene by treatment with dimethylamine in one step via Mannich reaction, was used to fabricate a new calix[4] arene-embedded polysulphone membrane (calix@membrane). Its structure and surface morphology were determined using thermogravimetric analysis and scanning electron microscopy, and elemental analysis techniques. Moreover, a Donnan dialysis system was employed to investigate Cr(VI) transport efficacy of calix@membrane at different pH values. Results showed that calix@membrane represented a promising transport capability for HCr2O7- due to their efficient complexation behaviour.
