Magnetic Activated Carbon Production from Lignin and Ferrous Salts : Process Modification for Enhanced Phosphate Adsorption from Aqueous Solutions

Sammanfattning: The treatment and control of superfluous aqueous phosphate is a critical task in environmental management. Magnetic bio-activated carbon is a good adsorbent for physical adsorption methods with several environmental and economic advantages. A streamlined and new method for production of magnetic bio-activated carbon from lignin is finished and presented by Tong Han. To enhance the phosphate adsorption and find the optimization process for mac production from lignin, it’s necessary to investigate influence of process parameters on the quality of the final products systematically. In this work, four different modification of process are used to investigate the influence of process parameters on the quality of the final products systematically, which shows how the proportion of iron oxides, the dispersion of iron oxides and the degree of activation influence the capacities. And the maximum capacity is around 50mg/g, which is a relatively high improvement.
