【 摘 要 】

The preparation process and method of magnetic water hyacinth(MBC) were conducted, and the morphological structure and surface characteristics of biochar were characterized. The optimal MBC preparation method was obtained under different carbonation temperatures, impregnation times, and mass ratio of potassium carbonate to water Gourd: carbonization temperature is 450 °C, iron nitrate concentration is 0.2 M, and the mass ratio of potassium carbonate to water hyacinth is 0.5:5.
