| Abstract |
|
A simple procedure to study adsorption principles is presented. The solid–liquid system consists of glass microspheres and aqueous solutions of an organic dye, Crystal Violet. With this experiment students determine an adsorption isotherm and analyze the dynamic behavior of a percolation column, carrying out a breakthrough experiment in a laboratorial setup. The most important percolation parameters are measured and modeling calculations are performed. Conclusions are drawn by comparing experimental data and the theoretical previsions.

Instructions for the instructors, including questions for the oral quiz, and the Matlab code, version 6.1, are available.
