2. (3.5 pts) An isotherm analysis was performed on iron- chitosan crosslinked polymer (CH-Fe"-Cl) and an aqueous solution of Phosphate[PO.]. Six beakers were used each containing 10 mg of CH-FE"-CL and 10 ml solution of varying initial concentrations of phosphate [PO]. After allowing the system to equilibrate for 6 hours analysis of the aqueous phase showed the following results: Adsorption Capacity qe for CH-FE- Phosphate concentration after CL (mg/g) absorption (mg/mL) 2.5 |0.25 5 101.9 15 3.7 20 4.0 10.50 Fit this data to the Langmuir isotherm and determine the maximum adsorption capacity (max and the affinity constant b.
