Abstract：In order to alleviate the enormous pressure that waste bagasse puts on the environment,BGO was prepared from waste bagasse.With Ca2+crosslinked SA as the first network and BGO as the heterogeneous nucleus for the second network,the PVA/SA/BGO double-network hydrogel spheres were constructed with the help of freeze-thaw method.The structure,morphology and adsorption properties of the PVA/SA/BGO double-network hydrogel for the organic dye crystalline violet(CV)were investigated.The results show that the obtained BGO has a lamellar structure and abundant oxygen-containing groups.The maximum adsorption amount of PVA/SA/BGO double-network hydrogel toward CV is 460.21 mg·g-1,and the adsorption process is in accordance with the Langmuir adsorption model and the pseudo-second-order kinetics model.
