Magnetic Porous Carbon from Biomass for Malachite Green Removal

Abstract

For years, environment protection, especially how to purify industrial and agricultural wastewater, has been a disputable issue. The scarcity of water resources increases the urgency of wastewater recycling. Meanwhile, emitting wastewater into rivers and farmland deteriorated environmental issues. To solve this problem, a low-cost and efficient way to produce porous carbon which can adsorb organic solute and then be removed is being discussed in this report, aiming to separate organic pollutants from wastewater. In this report, ferric chloride, potassium carbonate, and biomass (like sawdust) are used to fabricate porous carbon. These ingredients all low-cost and easy to be found in usual laboratory, suggesting that it is simple to imitate this method. Porous carbon produced in this method has excellent specific surface area of 1517 m2/g, which has an adsorption capacity for MG (malachite green) aqueous solution of 988.6 mg/g in maximum.
