A modified banana peel had excellent sorption capacity and environmentally friendly capacity was developed by esterification modification method with waste banana peel as substrate,glacial acetic acid as modifier,N-bromosuccinimide as catalyst.This method provided a factual basis for the feasibility of agricultural waste recycling.The experiment systematically researched the conditions affecting the esterification modification.And more,orthogonal experiments were carried out to explore the optimal preparation conditions of the materials.The results shown that the oil adsorption capacity of the material can be increased by more than 4 times when the solid-liquid ratio was 1∶40,the catalyst mass fraction was 5g/mL,the reaction time was 4h,and the reaction temperature was 100℃.Furthermore,the banana peel before and after modification were characterized by BET and FT-IR.Rougher surface and appearance of acetyl group of characteristic peak after esterification showed the feasibility of esterification modification of banana peel.
