Polymer Inclusion Membrane (PIM) has been widely used to remove heavy metal from aqueous solution. However, application of PIMs on dye removal is scarcely reported. The potential of CTA PIMs with Aliquat 336 to remove dye was discovered recently and this have attract researcher attention. In this study, CTA PIMs with Aliquat 336 was used to extract an anionic dye, Congo red from aqueous solution. The CTA Aliquat 336 PIM consists of cellulose triacetate (CTA) as base polymer and Aliquat 336 as carrier. The CTA PIMs was characterize by Fourier Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), water uptake and Ion Exchange Capacity (IEC). Important parameters that affect extraction capacity were studied such as Aliquat 336 concentration (0, 20, 30, 40 and 50 wt. %) pH of Congo red (2, 4, 6, 8 and 10), Congo red initial concentration (2, 4, 6, 8 and 10 ppm), temperature (27, 30, 40, 50 and 60℃) and stirring speed (150, 200, 250,300 and 350 rpm). Under an optimized condition (50 wt. % Aliquat 336, pH 2 of Congo red, 2 ppm of Congo red, 30℃ and 150 rpm), 87 % of Congo red was successfully to remove by CTA Aliquat 336 PIM after 24H.
