摘　　要：Amyloid fibrils derived from different proteins have been proved as a promising material for adsorption of various pollutants from wastewater,which showed advantages of low cost and eco-friendliness.However,most of the amyloid fibrils derived from animal-based proteins with high environmental footprint,while more sustainable amyloid fibrils derived from plant materials are desirable.In this study,a plant-derived amyloid fibril was extracted from the commonly used wheat flour with a simple and scalable protein purification and fibrillization process.Interestingly,the amyloid fibrils showed good adsorption capacity towards typical organic dyes(Eosin Y(EY)and Congo red(CR))from contaminated water.Adsorption kinetic analysis indicated the adsorption process to EY or CR by wheat flour amyloid well fitted with a pseudo-second-order model.The adsorption also followed a Langmuir isothermal model with adsorption capacities of 333 mg/g and 138 mg/g towards CR and EY,respectively.This work demonstrated the feasibility to utilize the plant-based amyloid fibril for organic dyes removal from contaminated water,which provided an affordable,sustainable and scalable tool for organic dyes removal from wastewater.
