1) Isotherm study of groundwater soil sample was conducted at 8 C. Therefore, 20 g of soil was spiked with benzene and toluene in a 450 mL jar and then 405 mL organic free water added to the spiked soil. The set of jars were kept in the fridge at 8 C overight. Samples were mixed during the incubation and analyzed by GC/MS next day. (12 pts) Isotherm info for Benzene: Initial Concentration (mg/L) 0 1 3 6 12 Isotherm info for Toluene: Initial Concentration (mg/L) 0 1 3 6 12 Final Concentration (mg/L) 0 0.05 0.12 0.17 0.514 Final Concentration (mg/L) 0 0.139 0.514 0.874 2.453 a) Make a table to report all the necessary calculations according to Freundlich isotherm b) Use the computer to plot the data to generate the linearized form of Freundlich model and determine the values for the constants
