The experimentally obtained methanol adsorption isotherms on the two activated carbons at the three temperatures considered here are shown in Figure 3. Because the isotherms at consecutive temperatures are relatively close, it is important to ensure the difference between two consecutive isotherms is statistically larger than the uncertainty in the isotherm data for either isotherm. To address this issue, adsorption isotherms for both adsorptives were repeated at 25 °C and the repeated isotherms are shown in Figure 3. The repeated adsorption isotherms essentially overlap and the difference between them is less than the difference between the amounts adsorbed at different consecutive temperatures.
