摘要：

It is vital to characterize the adsorption dynamics in oil-gas reservoirs and pollution control industry. Terahertz (THz) spectroscopy was used to study the adsorption of the water molecules in active carbon. The absorbance at selected frequencies and the first principal component scores over the whole THz range were related to the corresponding time lengths. The collective tendency expressly tracked the dynamics of water adsorbed in active carbon pores. Therefore, THz technique can be used as a promising tool to monitor the adsorption issues in petroleum and environment fields.
