Synthesis of Novel Magnetic Biochar Using Microwave Heating for Removal of Arsenic from Waste Water

Novel magnetic biochar has been successfully synthesized by using microwave technique, using discarded materials such as Empty Fruit Bunch (EFB). The optimized conditions for the best novel magnetic biochar synthesis are at 900 w reaction power, 20 min reaction time, and impregnation ratio 0.5 (biomas:FeCl3) The details physical and chemical analyses of novel magnetic biochar were found to be in good agreement with the hypothesis. These newly produced magnetic biochars have a high surface area 890 m2/g and that leads to highly efficient in the removal of arsenic (87%) from aqueous solution. As for new invention, magnetic biochar can be directly produced using microwaves heating by a single stage of activation compared to the conventional method.
