Zn-Al layered double hydroxide and Zn-Al/Biochar have been Synthesized. Synthesized material was characterized using XRD, FT-IR, SEM, BET and TG-DTA. The material is used as an adsorbent for methylene blue dyes. The results of the XRD analysis showed that the Zn-Al layered double hydroxide and its composites have diffraction at 10,150°. The results of the FT-IR analysis showed that the vibrati…
