We further explored the effect of temperature and humidity on the adsorption of volatile organic compounds on activated carbon. The equilibrium adsorption capacity of methylene chloride and water on activated carbon at different temperatures and different absolute and relative humidity was determined by dynamic adsorption method using dichloromethane as the target. The temperature and humidity are controlled by the temperature regulation and humidity control process. Regression analysis was performed on dichloromethane concentration, temperature and absolute humidity. The regression analysis yielded the equation: Y=0.01138X 1 -0.000968X 2 -0.000326X 3 +0.0492.
