Internet-Enabled Experiment for Demonstrating Contaminant Adsorption to Activated Carbon

Abstract

Exposure to laboratory experiences is valuable for students in all engineering disciplines. Because of spatial constraints or physical limitations, not all engineering students can obtain hands-on involvement with relevant experimental apparatus and laboratory procedures in their curriculum. However, all engineering students should have familiarity with conducting experiments, and collecting and analyzing experimental data. An Internet-enabled experimental apparatus that demonstrates contaminant adsorption to activated carbon was developed. The hardware and software permitted remote students to operate the apparatus by distance through the Internet. Using the Internet, the students were able to collect data for further analysis. The experiment was implemented in an introduction to civil engineering course, primarily consisting of first and second-year civil engineering students with broad civil engineering interests (e.g., structural, geomechanics, environmental). Through appropriate assessments, the experiment was found to significantly facilitate the students’ understanding of adsorption phenomena. The ability to operate remote laboratory tests can augment the educational experience of students who would otherwise not have a laboratory opportunity, such as distance learners and physically challenged students.
