Abstract

Using calcination-hydration method, a new type of solid adsorbent Mg₂Al-LS-LDH was prepared through water soluble sulfonated lignin loading on the LDHs surface. The structure of the composites were characterized by XRD and IR, and its adsorption performance was studied. The results showed that the sulfonated lignin didn't enter into the interlayer of LDHs, but bond with the surface hydroxyl of the LDHs. The adsorption rate of copperion was fast and the adsorption rate was 30 min, closing to the adsorption equilibrium, the removal rate was 92.2%, the adsorption capacity reached 36.88 mg/g. In addition, the optimum adsorption conditions were adsorption time 6 h, pH=5, the mass of adsorbent 0.0500 g, adsorption temperature 25℃.
