Surface modification of biochar by using steam activation

Water pollution has been a major problem not only to the citizens but also the environment. In order to reduce water pollution and also other pollution, biochar had been choosed as an adsorbent. Surface modification by using steam activation had been performed in order to enhance the efficiency of removal of pollutants from water by increasing the surface area. Two objectives are identified to counter the problem statement stated in the research background which are to improve the quality of biochar which involves the modification process and to modify the surface morphology of the biochar.
