▎ 摘  要

NOVELTY - An active carbon based on normal temperature laser induction, comprises 50-200 pts. wt. activated carbon, 1-10 pts. wt. laser sensitive material, 10-300 pts. wt. activating substance, and 2000-5000 pts. wt. solvent. USE - Active carbon based on normal temperature laser induction, used in pore-forming method (claimed) for air purification and sewage treatment. ADVANTAGE - The method can realize rapid and efficient production of porous activated carbon under normal temperature conditions. The method has characteristics of low cost, low energy consumption, normal temperature preparation conditions, and simple operation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for pore-forming method of active carbon based on normal temperature laser induction, which involves: (a) arranging active carbon, laser sensitive material and activating substance in a solvent, and ultrasonically mixing to prepare a mixed solution; (b) placing the mixed solution in oven at 110℃ and drying for 24 hours; and (c) paving the prepared active carbon mixture into a thin layer with thickness of 1 mm, irradiating with laser, adjusting laser power, so that the laser sensitive material absorbs laser and generates heat energy, promoting thermal decomposition of activating substance loaded on active carbon, for forming a rich pore structure on surface of active carbon.
