Date palm leaf mid-rib (DPLM) biochar has been examined as an adsorbent in comparison with another two adsorbents (Corn stovers biochar and local commercial coal) to test for its physical & chemical adsorption properties. DPLM and Corn Stover biochars have been prepared in a muffle by carbonization at 450 ⁰C for 2 hrs, then activation by sulphuric acid 10% at 40-50 ⁰C, then washing well with distilled water until no excess sulphate ions are longer present. Different adsorption experiments have been done to the adsorbents complete with the commercial coal. Methylene blue dye was used for the adsorption experiments. The results shows that the DPLM activated biochar at alkaline pH gave the maximum adsorption (99.7%). The physical characterization experiments done to the DPLM revealed that it has a large surface area, and very large pore volume.
