The Illinois EPA has ordered a local pesticide storage facility to remediate contaminated groundwater in the area of their facility. The water contains 0.6 mg/L of ß-Endosulfan. As a preliminary step in this project you are to construct both the Langmuir and Freundlich isotherms for the data provided. Then estimate the value of q_e at a concentration of 0.01 and 0.005 mg/L using both the Freundlich and Langmuir isotherms. Compare the results from the two methods. Which gives a better fit to the data?

The volume was 250 mL. This data is for the adsorption of ß-Endosulfan onto Filtrasorb 300, an activated carbon produced by the Calgon Corporation. Download this spreadsheet and complete it. Add worksheets for each graph. Note: To download the file, right click and choose "Save File As. . ."
