摘要

In this work,we demonstrate that eggshell membranes(ESM)can be successfully functionalized with extracts from orange peel or broccoli leaves and stems,in order to create a completely food waste-based adsorbing material,ideal for the removal of hexavalent chromium(Cr(VI))from water.This approach represents a proof-of-concept example of simultaneous solution to a couple of major global challenges:assuring good quality water and recycling food waste.The working principle of the presented system is based on a synergistic interplay between the ESM functional groups(in particular,protonated amino and carboxylic acid groups)and the organic acids contained in vegetable extracts and it enables to obtain a device that works efficiently in real world conditions.
