Question 2 (a) Explain how an ion-exchange separation process works with an example. (b) Equilibrium isotherm data for adsorption of glucose from an aqueous solution to activated alumina are as follows: c (g/cm3) q (g solute/ g alumina) 0.005 0.0088 0.020 0.027 0.105 0.195 0.025 0.055 0.080 0.083 0.127 0.129 Show that the Langmuir isotherm fits the data and find the constants of the equation. (c) An ion-exchange process using a resin to remove copper ions from an aqueous solution is conducted in a 2.5 cm diameter column and 50 cm high. The flow rate is 1.5 l/min and the breakpoint occurred at 10 minutes. Integrating the breakthrough curve gives a ratio of usable capacity to the total capacity of 0.6. Design a new tower that will be 4.0 m high and operate at 4.5 I/min. Calculate the new tower size and break-point time.
