Honeycomb activated carbon It can be used directly or placed in the purification cabinet and adsorption bed. If the concentration of waste gas is high, two purification cabinets and adsorption beds can be used alternately. Pay attention to avoid excessive temperature during use, which will reduce the honeycomb Activated carbon If the use environment contains high dust and tar, the front dust filter should be installed before the use of large honeycomb activated carbon to achieve proper use effect and long service life.

Honeycomb activated carbon has stronger adsorption capacity in water than in organic solvents. The adsorption capacity of compounds with more polar groups is greater than that of compounds with less polar groups. The adsorption capacity of aromatic compounds is greater than that of aliphatic compounds; The adsorption capacity of high molecular weight compounds is greater than that of low molecular weight compounds. Therefore, for the preparation with low content of main drug or easy to be absorbed by active carbon, the amount of active carbon should be controlled at 0.05% (w/v) (the amount should be as small as possible), and the amount of main drug should be appropriately increased through calculation.
