Using aniline and environmentally friendly chitosan as raw materials, MnFe 2 O 4 with photocatalytic properties was introduced and in-situ polymerization was used to prepare Cht/PANI/MnFe 2 O 4 . The Cht/PANI/MnFe 2 O 4 was characterized by FTIR, SEM, XPS, XRD, BET and TGA. The experiment on the influence of pH on the adsorption capacity of the material shows that an acidic environment is conducive to the adsorption of fuel by the adsorbent. The zero charge point (pH PZC ) on the adsorbent surface is obtained at pH 6.45. The adsorption kinetic ...
