Abstract
The environmental problems and solutions represent a priority for
scientific community. Water pollution with drugs is a contemporary problem, which
needs to be made aware of and solved by ecological means. Also, ecofriendly methods
of decontamination of polluted waters are a topic of study for students from natural
sciences. The present work proposes an eco-friendly method of filtering drug-polluted
water, which can be used in students' experimental laboratories related to environmental
protection. This paper presents the use of clay, micronized activated zeolite and
granular activated carbon as filters for the removal of drugs from wastewater. Using the
UV-VIS spectroscopy technique, the degree of decontamination of water polluted with
N-Acetyl cysteine is evaluated. The combination of the three filter materials is the most
efficient one having the greatest absorbance capacity of 71%. Students using these
methods, besides better understanding the chemical and physical notions related to the
experiment, will also learn about sustainability and environmental protection.
