Water pollution has been one of the
major issues of the present
time. It is essential to educate students regarding this issue and
its possible solutions. In this article, a demonstration of a typical
adsorption-based water cleaning process is presented. The removal
of methylene blue (MB) and detergent from a aqueous solution is demonstrated
using rice husk as the adsorbent. Quantification of the MB removal
was achieved with the help of a smartphone-based colorimetry process.
This demonstration would be helpful to students for understanding
the adsorption process, calibration curves, and waste management.
The kinetic study of adsorption will help students learn various kinetic
models and their applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
