Which method is best for measuring adsorption capacity (x or W) for ACF?

02 February 2014 1 3K Report

How can you determine constant ( D , W0, a and b ) in DR and DA equation for adsorption kinematics.

Hello Hitesh,

I am not sure I know what ACF is. However, if you want to determine the adsorption capacity of any sorbent, then model your results on Langmuir or Freundlich models (the most popular models). Alternatively you can model kinetics data of a sorbent using Lagegren pseudo first or second order equations. Check out my papers below:

DOI 10.1007/s11356-013-2305-6.
