| Abstract | : | In this research, chitosan/silica/polyethylene glycol (Ch/Si/P) composites membrane was used as selective adsorbent of rhodamine B from aqueous solution. This study involved by preparation Ch/Si/P composites membrane. The structure and surface morphology of Ch/Si/P composites membrane was characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy. Batch adsorption experiments were conducted with various contact time and rhodamine B concentrations to evaluate the adsorption kinetics and thermodynamics. Results show that adsorption fitted to Langmuir model and followed a kinetic model of pseudo-secondorder. The adsorption capacity of rhodamine B onto the Ch/Si/P composites membrane is 0.052 mmol/g. The relative selective factor (?f) values of rhodamine B/Cu and rhodamine B/Pb are 3.53 and 0.42. This means that rhodamine B can be determined even in the presence of Cu interference, but can't be determined in the presence of Pb interference. |
