Abstract
. Obviously, the adsorption proficiency of ion-activated carbon markedly exceeds that of carbons activated physically or chemically. Of all materials investigated in this paper, ion-activated carbon D consistently exhibits superior performance, maintaining a ciprofloxacin removal rate nearing 100% at 40 °C. Remarkably, the maximum regeneration frequency of ion-activated carbons can reach up to 10 cycles. In conclusion, these five ion-activated carbons, demonstrating superior pore-structure parameters and adsorptive capacities, outperform those prepared through physical/chemical methods. They emerge as promising contenders for new, high-performing adsorbents.
