摘要
In this study a combined approach based on known theoretical solution of a dynamic model, where the parameters of the model are determined from the experimental data at high concentration of an adsorbate is used. The breakthrough time for the required conditions is calculated from the extrapolation of the experimental data fitted by the theoretical equation derived from the model. Parameters of the model used, e.i. kinetics coefficient and the capacity of an adsorbent are found by fitting theoretical and experimental breakthrough curves obtained for high concentrations of H2S. The results are compared to those collected in “real life” long term tests of coconut shell based activated carbons at North River Water Pollution Control Plant in New York City.
