The KIST research team observed magnetic porous carbon composite materials in the transmission electron microscope. Researchers tested the efficiency of the porous carbon composite in terms of its ability to adsorb "tetracycline," or the antibiotic used to treat bacterial infections, from the water. Tests showed that the newly developed material was able to remove 100% of the tetracycline in about 90 minutes under general water conditions (pH 6), with an adsorption rate of 671.14 mg/g, which is a rate superior to that of previously developed adsorbents. In order to assess the reusability of the porous carbon composite, the adsorption-desorption process was conducted five times. Even after repeated use, the material maintained 90% of its adsorption properties, indicating a high degree of stability and wide applicability for water treatment.
