Abstract

Adsorption is one of the most common physicochemical treatment processes in environmental engineering. Faculty typically teach this process by explaining figures and equations in texts, which can limit learning. The five minute classroom demonstration presented here replicates the adsorption experiment and data analysis, which may engage students and enhance learning without imposing substantial demands on student time. Students observe removal of Crystal violet dye or food coloring by activated carbon in real time in a column demonstration. Simultaneously, data from an adsorption experiment is collected in an accelerated video format and an animated PowerPoint presentation illustrates how experimental data is used to quantify Isotherm Model parameters. Results from the Crystal violet adsorption experiment and isotherm model parameters are presented along with an in-class example problem.
