The reduced human hair keratin powder extracted from human hair after hydrolysis was added to PEO/PVA solution,and the human hair keratin/PEO binary composite nanofiber membranes and the human hair keratin/PEO/PVA ternary composite nanofiber membranes were prepared by electrospinning.The adsorption performance of the membranes to reactive black KN-B was investigated by comparing the adsorption kinetics and thermodynamics of different human hair keratin composite nanofiber membranes to reactive black KN-B.The results showed that the adsorption of the membranes to reactive black KN-B was in accordance with Langmuir adsorption model.The maximum adsorption capacity of the human hair keratin/PEO/PVA ternary composite nanofiber membrane with smaller fiber diameter reached 132.01mg·g-1.Therefore,it had a good application prospect in the treatment of dyeing wastewater and printing wastewater.
