▎ 摘　　要

NOVELTY - Preparing kappa-carrageenan/graphene oxide gel pellets, comprises (i) mixing kappa-carrageenan, graphene oxide and water to obtain gel, where the concentration of kappa-carrageenan in gel is 0.5-1.5 wt.%, and (ii) adding the obtained gel into calcium chloride solution in dropwise manner, and pelletizing to obtain final product. USE - The gel pellets are useful in wastewater treatment (claimed). ADVANTAGE - The pellets: contain more pores and pleats to provide large specific surface area for adsorption of organic dyes; and have improved adsorption.
