Research on adsorption performance of magnetic bio-char for tetracycline in water

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