Facile Hydrothermal Preparation of Carboxymethyl Chitosan Functionalized Hydrotalcite Composite with Enhanced Adsorption Capacity for Cu(II) Ions
In order to enhance the adsorption capacity of hydrotalcite material for heavy metal ions, the LDH/CMC composite was prepared by a simple hydrothermal method. The XRD pattern showed that the presence of CMC has no obvious influence on the crystal structure of hydrotalcites. The FT-IR and UV-vis DRS analyses showed that the CMC functionalized surface has been obtained. The SEM and BET/BJH showed that the morphologies, textural and surface chemical properties of LDH were affected remarkably after the introduction of CMC. The weight percentage of CMC in the LDH/CMC composite was estimated to be about 17.4%. The adsorption experiments showed the LDH/CMC composite exhibited high efficiency in the Cu(II) removal at pH > 6.5, affording Cu(II) removal rates of 92.3%. The results demonstrated that the LDH/CMC composite was a suitable adsorbent for Cu(II)-contaminated wastewater treatment.
