Problem 6. B-Endosulfan is an organic insecticide commonly used on vegetables and ornamental flowers. A carbon adsorption test was performed to evaluate adsorption of B- Endosulfan to activated carbon. The data from the test are listed in the table below. The initial B-Endosulfan concentration for the test was 0.082 mg/L. The flask volume was 250 mL (0.25 L). a. Calculate the Langmuir constants. b. What q. (mass adsorbed/mass of carbon) would be required to attain a contaminant concentration of 0.02 mg/L? Note that all graphs of data should be prepared using appropriate software (eg., Excel, Matlab, etc.), and sample calculations should be provided for any work done using a spreadsheet

Problem 6. B-Endosulfan is an organic insecticide commonly used on vegetables and
ornamental flowers. A carbon adsorption test was performed to evaluate adsorption of B-
Endosulfan to activated carbon. The data from the test are listed in the table below. The initial
B-Endosulfan concentration for the test was 0.082 mg/L. The flask volume was 250 mL (0.25 L).
a. Calculate the Langmuir constants.
b. What q. (mass adsorbed/mass of carbon) would be required to attain a contaminant
concentration of 0.02 mg/L?
Note that all graphs of data should be prepared using appropriate software (e.g., Excel,
