Due to a large amount of biomass remaining in Malaysia, biochar has recently received great attention. Biochar is extensively used worldwide to improve the environmental aspects of soil fertility and water quality. the Two raw biomass materials from different sources (aluminosilicate: rice husk and agricultural lignocellulosic waste: kenaf fiber). The properties of the optimal mixing ratio of biochar were investigated by using proximate analysis, ultimate analysis, thermogravimetric analysis, surface area and pore volume determination, Fourier Transform Infrared Spectroscopy analysis, X-ray diffraction, and Scanning Electron Microscopy. According to the proximate analysis, ash content is increasing while the moisture content fixed carbon and volatile matter decrease. Based on the BET characterization finding, the surface area is increased proportionally as increasing the mixing ratio RHB: KFB (0.8:0.2, 0.5:0.5, 0.2:0.8). The SEM images showed that both biochars are suitable sources of blending because of the differences and the availability of good adsorbents. Based on this study, RHB and KFB as pure biochar have a great potential to be applied as an adsorbent. However, blending is not giving the desired result to be used as an adsorbent.
