It is always exciting to bring nonengineering or first year engineering students into the laboratory – they can learn a lot about engineering by working in the space, but the experiment needs to be safe and accessible. This paper describes an adsorption experiment with safe and easy data collection. The analysis can be simple (graphing disappearance of a dye as a function of time) or complex (calculating equilibria, rate expressions and thermodynamic quantities). Groups of students can collect data under different conditions and tell a more complete story about the adsorption process.
