| Research Abstract |
From the viewpoint of resources recovery as well as environmental protection, the investigation aboutremoval and recovery of heavy metals (particularly rare earth elements (REEs) and uranium (U)) using the seaweed and shell biomass was performed in this work. Consequently, the following matters have been mainly clarified. (1) Adsorption isotherms for REEs using the seaweed and shell biomass can be generally described by Langmuir isotherms more satisfactorily. It indicates that the adsorption occur predominantly on the monolayer. (2) The cracks area containing protein in the shell biomass shows high absorption capacity for REEs. Then, this study suggested that the seaweed and shell biomass could be efficient sorbents for REEs.
