Abstract: Durian, originating from the Durio Zibethinus genes is one of the widely consumed fruits in South East Asia especially in Malaysia, Indonesia, Thailand, Singapore and Philippines. Durian’s rind was found to be abundantly available in Malaysia due to the high consumption of durians by the locals. Durian rinds were opted to produce magnetic biochar in the presence of iron oxide solution by employing the pyrolysis process in a muffle furnace at a pyrolysis temperature of 700˚C and pyrolysis time of 20 minutes. The pyrolysis process was carried out in a condition of absence of oxygen in the muffle furnace by generating a vacuum condition without utilizing any carrier gas. Magnetic biochar which were produced with a surface area of 790 m2/g successfully provided a 95% removal of 30 mg/L methylene blue from aqueous solution with a maximum adsorption capacity of 87.32 mg/g at an optimum condition of pH 9 of stock solution, adsorbent’s dosage of 0.5 gram, agitation speed of 120 rpm and contact

Abstract: Synthesis of mangosteen peel based magnetic biochar was carried out in Muffle Furnace at zero oxygen condition at 700 C heating temperature for 20 minutes. The biomass for pyrolysis was prepared through oxidation process with Iron Oxide ions mixed with 0.4M KMnO4 and 0.4M HNO3 acid. The process optimization was determine by manipulating agitation speed (rpm), time (min) and pH value by using Design Expert software version 7.0. The statistical analysis revealed that the optimum condition for removal of Zn2+ ions were at adsorbent dosage of 0.5 g, pH 9.0, agitation speed and time were 125 rpm and 45 min respectively. The maximum adsorption capacity opted for the adsorbent with surface area 730 m2/g was 86.33 mg/g. For the initial concentration of 30 mg/L, the maximum removal percentage obtained was 93%. The surface adsorption characteristics were determined by Langmuir and Freundlich constant which were 0.0461 L/mg and 12.283 L/mg respectively. The research outcome indicates that the Man
