What is the V in this equation qt=(Co-Ct)V/M if I am doing my...
The well-known equation for calculating amount adsorbed on adsorbent in solutuion is qt=(Co-Ct) V/M, where Co the initial concentration, Ct concentration at time t, Volume of solution used, M is the mass of adsorbent used. This equation is always explain when dealing with solution (e.g adsorption of dye by solid adsorbent).But, I have a set of data of adsorption of formaldehyde gas adsorbed by solid adsorbent. Does the Volume is the volume of the test chamber I used (height)x (width)x(length)? Or is it the volume of formaldehyde that i used (in liquid form) to let it vaporize inside the test chamber?Note: I used formaldehyde solution that vaporize in the chamber to give the required initial concentration of formaldehyde.I really hope somebody can answer my question. Thank you.
