<p>PURPOSE:To improve adsorptive performance of active carbon for harmful gases in the atmospheric air by depositing additionally polyalkyleneimine to the active carbon. CONSTITUTION:0.1-50wt% polyalkyleneimine such as polyethyleneimine having 300-100,000 average mol.wt. is deposited to active carbon having >=0.15cc/g pore volume for 30-300Angstrom pore size. For the deposition of polyalkyleneimine, a soln. of polyalkyleneimine is applied by spraying and then drying, or by other process.</p> |
