Abstract
Magnetic β-cyclodextrin pyrolysis products at 500°C were prepared from β-cyclodextrin pyrolysis products as raw materials, and the adsorption performance of magnetic β-cyclodextrin pyrolysis products on Cu2+ was studied by nitrogen nitriding. this study provided a theoretical basis for the preparation of highly effective adsorbents and the prediction of their adsorption performance on Cu2+. The results show that the adsorption behavior of Cu2+ by magnetic β-cyclodextrin pyrolysis products conforms to the pseudo-second-order kinetic equation. The isothermal adsorption curve conforms to the Langmuir equation, and the maximum adsorption capacity is 405.99mg·g−1.
