Adsorption of acetone from aqueous solution on activated carbon can be represented by the Langmuir equation:
\[
\frac{q}{C} = \frac{1}{0.146} + \frac{0.190}{C}
\]
where \( q \) is the adsorbate loading mol/kg, and \( C \) is solute concentration in aqueous solution mol/m³. The maximum adsorbate loading in kg acetone/kg carbon is
Show Hint
- 0.0755
- 1.3014
- 0.1658
- 0.0096
The Correct Option is A
Solution and Explanation
- From the Langmuir equation, we know that the maximum adsorbate loading occurs when \( C = 0 \), i.e., when the concentration is zero.
- At this point, the equation simplifies to: \[ \frac{q_{{max}}}{C} = \frac{1}{0.146} \]
- Rearranging this gives the maximum adsorbate loading as \( q_{{max}} = 0.0755 \, {kg} \, {acetone/kg carbon} \).
Conclusion:
The maximum adsorbate loading is 0.0755, as given by option (A).
