12.1-1.	Equilibrium Isotherm for Glucose Adsorption. Equilibrium isotherm data for adsorption of glucose from an aqueous solution to activated alumina are as follows (H3): C (g/cm3) 0.0040 0.0087 0.019 0.027 0.094 0.195 q (g solute/g alumina) 0.026 0.053 0.075 0.082 0.123 0.129 Determine the isotherm that fits the data and give the constants of the equation using the given units.
A1:	Ans. Langmuir isotherm, q = 0.145c/(0.0174 + c)
12.2-1.	Batch Adsorption for Phenol Solution. A wastewater solution having a volume of 2.5 m3 contains 0.25 kg phenol/m3 of solution. This solution is mixed thoroughly in a batch process with 3.0 kg of granular activated carbon until equilibrium is reached. Use the isotherm from Example 12.2-1 and calculate the final equilibrium ...
