QUESTION 2 Activated carbon is tested to purify effluent water from a biological process. The equilibrium data in terms of total organic carbon (TOC) are given below. Determine which isotherm between the Langmuir and Freundlich fits the data and give the constants of the equation using the given units. 9 solute on activated carbon, (mg/mg) Final TOC (mg/L) 0 10 0.185 6.3 0.167 3 0.147 1.5 0.083 0.4 0.041 0.15 0.017 0.05 The Freundlich isotherm is given by: q=kcn Where, K and n are constants that must be determined experimentally. 2 The Langmuir isotherm is given by: 90c q= K+c You may use excel for all graphical solutions.
