Boron Adsorption by Cellulose Supported Layered Double Hydroxides

Article Preview

Abstract:

Carboxymethyl cellulose (CMC)-supported layered double hydroxides (CMC-LDHs) were synthesized by ion exchange method. The raw cellulose, unsupported LDH and CMC-LDHs were characterized by XRD, and FTIR. The CMC-LDHs was applied to adsorb boron with batch adsorption in aqueous solution, and the conditions influencing its adsorption amount were investigated. The experimental results showed that the CMC-LDHs had higher adsorption amount than the precursor, and the adsorption amount increased with increasing the contact time, boron concentration, and the pH.
