Nitric acid surface treatment of activated carbon filter felt and cloth and method thereof

摘要

The invention is the special properties not only effective for the adsorption of these larger by giving increasing the content of the further expanded and functional groups the size of the micropores developed on the surface by treating the surface of the activated carbon fibers by using a nitric acid-molecular-weight substances and polar substances as selective absorption of the materials is also possible with, on the nitric acid surface treatment apparatus and the method for surface treatment of the activated carbon fibers,; Is installed in the thermostatic chamber, and is installed on the upper portion of the evaporator and, above the evaporator is formed with nitric acid injection port for injecting a nitric acid on one side, and the shelf can hold the activated carbon fiber bowl contained the activated carbon fibers and the an exhaust pipe that is connected to a rack and, installed in the middle of the exhaust pipe which comprises the nitric acid absorption tank to absorb nitric acid.
