Methods for the rapid removal of chemical warfare agents are of critical importance. In this work, a porous activated carbon material (C-PAC) was prepared from chitosan flakes via single-step potassium carbonate (K2CO3) activation for the prompt adsorption of dimethyl methylphosphonate (DMMP). C-PAC samples were prepared using different carbonization temperatures (350, 550, and 750 degrees C) at a constant K2CO3/chitosan ratio (1:2) and using different activator ratios (K2CO3/chitosan ratios of 1:0.5, 1:1, 1:2, and 1:3) at 750 degrees C. Furthermore, we evaluated the effect of preparation conditions on the adsorption capacities of the various C-PAC materials for DMMP under ambient conditions (25 degrees C). Notably, for the C-PAC material prepared at 750 degrees C using a K2CO3/chitosan ratio of 1:2, the DMMP adsorption was saturated at approximately 412 mgg(-1) carbon after 48 h. The good performance of this material makes it a potential candidate for use in remedial applications or protective gear.
