(1)The successful adsorption of glyphosate by modified shell powder/Ce-N-TiO2 and the formation of negatively charged inner layer complexes on the surface of modified shell powder/Ce-N-TiO2 were demonstrated by SEM, zeta potential, FT-IR and XPS characterization. (2)The effects of pH, contact time and dosing amount on the removal rate were analyzed by response surface analysis, which indicated that the interaction of two-two factors had significant effects on the adsorption and removal of glyphosate. (3)Modified shell powder/Ce-N-TiO2 adsorption of glyphosate was in accordance with the quasi-secondary kinetic model and Langmuir model, and the maximum adsorption amount was 66.98 mg/g. This paper is one of the phase results of the National Natural Science Foundation of China (No: 42071122), Hunan University Student Innovation and Entrepreneurship Training Program (S202111527011, S202011527003).

Glyphosate is a typical dissolved organic phosphorus that can cause adverse effects on plants, animals, and humans. Modified shell powder/Ce-N-TiO2 was synthesized by high-temperature doping, and the prepared modified shell powder/Ce-N-TiO2 was characterized and used response surface methodology to find out the optimum condition for adsorption removal rate. The zeta characterization indicates that the doping of Ce shifts the isotropic potential of the material to the right. The FT-IR and XPS characterization indicated that glyphosate was succes...
