Abstract

ABSTRACTMesoporous MCM-48 membrane was prepared on a low-cost circular-shaped ceramic support by a hydrothermal crystallization technique. The characteristics of MCM-48 powder and composite membrane were evaluated using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), porosity and water permeation test. The porosity and pore size of the composite membrane were found to be 22% and 0.142 µm, respectively. The MCM-48 composite membrane was investigated for the separation potential of FeCl3 from aqueous solution and a maximum rejection of 86% was obtained for a feed concentration of 250 ppm at lower pH 2.
