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 Mangosteen peel based magnetic biochar is a promising adsorbent for removal of Zn2+ ions from aqueous solution.
