Preparation and Characterization of Spherical Lignin/Polylactide Composite Adsorbent
The spherical lignin/polylactide (PLA) adsorbent was prepared by solvent evaporation. The dispersed phase contents, the PLA concentration and ratio of PLA to lignin on the diameter and mechanical strength of the PLA/lignin composite adsorbent spheres were investigated and the morphology structure and mechanical strength of the adsorbent were characterized by scanning electron microscope (SEM) and dynamic mechanical analyzer (DMA). The results showed that the adsorbent has porous structure, and the mechanical strength increased significantly as the ratio of PLA to lignin as 4:1.
