Antibiotics are emerging pollutants due to their continuous input in the ecosystem, resulting in antibiotic-resistant bacteria, which cause immunity to antibiotics. To prevent this contamination the use of sorbents seems promising. Biochar can be characterized as low-cost sorbent from agriculture, that can deliver solutions to a wide spectrum of challenges related to the release of antibiotics .This study aims to examine the sorption of seven antibiotic compounds, by two biochars produced, sludge and manure. Adsorption kinetic experiments were performed. UPLC-MS-MS measured residual antibiotics in solutions with the % removal being calculated. The research took place between July2018 and Feb2019 by high school students in Cyprus under surveillance of the Nireas-IWRC, University of Cyprus.
