Determine the Freundlich and Langmuir isotherm model parameters for the set of equilibrium adsorption data provided below. You may use linear regression, and plot Ce/Qad versus Ce for the Langmuir equation (qe = QadbCe)/(1+ bCe) and log qe versus log Ce for the Freundlich isotherm equation (qe = KF Ce"), or use non-linear fitting feature built in Excel. In your solution, you need to explain your procedure and circle your parameters. Q ad is the (monolayer) adsorption capacity for the Langmuir isotherm model. %3D Adsorption isotherm data: Carbon type, F-400; chemical: tetrachloroethene, temperature: 13.8°C Ce (umol/L): 15.7 qe (umol/g): 1246 1.27 489 0.396 298 0.225 250 0.161 213 Note: 1) Use the proper units for the isotherm parameters. 2) When you graph the isotherm data, do not connect the data points. 3) Provide the curve fitting (dashed line and isotherm parameters with 3 significant digits. 4) The x-axis and y-axis should be the bottom and the left sides of your figure. Please see below for a plot of isotherm.

Question
Determine the Freundlich and Langmuir isotherm model parameters for the set of equilibrium adsorption data provided below. You may use linear regression, and plot Ce/Qad versus Ce for the Langmuir equation (qe = QaabCe)/(1+ bCe) and log qe versus log Ce for the Freundlich isotherm equation (qe = KF Ce"), or use non-linear fitting feature built in Excel. In your solution, you need to explain your procedure and circle your parameters. Q ad is the (monolayer) adsorption capacity for the Langmuir isotherm model. Adsorption isotherm data: Carbon type, F-400; chemical: tetrachloroethene, temperature: 13.8°Č Ce (umol/L): 15.7 qe (umol/g): 1246 1.27 489 0.396 298 0.225 250 0.161 213 Note: 1) Use the proper units for the isotherm parameters. 2) When you graph the isotherm data, do not connect the data points. 3) Provide the curve fitting (dashed line and isotherm parameters with 3 significant digits. 4) The x-axis and y-axis should be the bottom and the left sides of your figure.
