A packed column is used to remove an organic contaminant (A) from an aqueous solution using adsorption onto activated carbon. Data has been captured for the solid concentration (mass of contaminant adsorbed per mass of activated carbon) as a function of the concentration of the contaminant in solution. A colleague is helping you assess the data and has suggested using the Langmuir adsorption model to analyze them. She has linearized the model, plotted the data, and obtained a slope and intercept. She leaves you the following note before leaving on vacation. "I plotted the data (1/CA vs. 1/q) and got a line 1/CA=m(1/q)+b with m=6.3051 and b=16.949. The data fit the line really well. Here's the Langmuir model - I don't remember how to get the parameters from the slope and intercept." q=K+CAq0CA What are the values of K and q0 corresponding to 1/CA=m(1/q)+b with m=6.3051 and b=16.949 ? q0=(kgA/kg) K=(kgA)/m3 eTextbook and Media Hint Attempts: 1 of 4 used Adsorption Process X Check your answer by seeing if it satifies both the Languir adsorption model and the mass balance. Using the values of K and q0 determined above, solve for the concentration in the water and the concentration on the carbon when 25.0m3 of a feed solution containing the contaminant at a concentration of 0.420kg/m3 is contacted with 25.0kg of fresh, clean, contaminant-free carbon. What is the fraction ( f ) of the contaminant removed from solution in the batch process
