High surface area, mesoporous materials were prepared for the removal of organic from water. Cellulose or polyacrylonitrile (PAN) were dissolved in 66 wt % of ZnCl 2. The pore size distributions could be controlled by the temperatures of heat stabilization and activation. The peak value of mesopore size was 20-40 Å. This material showed an enhanced adsorption capacity to humic acid from water. The low temperature activation resulted in a high content of oxygen-containing functional groups for cellulose-based material and nitrogen-containing groups for PAN-based material. These functional groups along with high surface area expected to improve the adsorption of polar organics, e.g., MTBE and humic acid, in water. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA 8/22-26/2004).
