| Popis: | In this paper, waste coconut shells are used as raw materials to prepare the corresponding bio-char (BC), and further prepare magnetically modified magnetic bio-char (MBC), and explore the adsorption of BC and MBC on the amount of adsorbent, adsorption time and pH. The recyclability of BC and MBC were contrasted. The results of the study found that compared to BC, the magnetically modified MBC has a larger specific surface area and richer functional groups, which provides more adsorption sites for the adsorption and removal of tetracycline. It can be used in different adsorbent dosages and adsorption times. Under the conditions of pH and pH, it shows better adsorption performance. In addition, MBC has better recycling properties than BC, which has higher application prospects. This research provides a theoretical basis for the utilization of waste resources and the removal of antibiotics in wastewater. |
