Preparation method and application of coupling agent surface modified orange peel derived carbon material

The invention discloses a preparation method and application of a coupling agent surface modified orange peel derived carbon material. The preparation method comprises the following steps: S1, cleaning, drying, crushing, grinding and sieving collected orange peel; s2, carrying out hydro-thermal treatment on the orange peel to obtain a precursor, washing and drying; s3, activating the precursor with concentrated sulfuric acid, washing and drying to obtain an orange peel derived carbon material; s4, carrying out surface modification on the orange peel derived carbon by using aminopropyltriethoxysilane, washing the obtained solid product, drying and grinding to obtain an aminopropyltriethoxysilane surface modified orange peel derived carbon material; according to the method, the orange peel derived carbon material can be subjected to surface modification, the surface structure of the orange peel derived carbon material is changed, so that the adsorption capacity of the material is improved, the method is simple, the cost is low, pollution is small, industrialization is easy to achieve, large-scale production is facilitated, and the material prepared through the method has very high value in application in the fields of substance adsorption and catalyst carriers.
