SEM-EDX characterization of iron-modified plum stones biochar

It has been shown that biochar, an inexpensive and eco-friendly material made by pyrolyzing biomass, has the ability to eliminate pollutants from water and wastewater. The efficacy of raw biochar as adsorbent and catalyst in advanced oxidation processes is limited, but it is significantly increased by modification. Various physical and chemical methods employed before, during, or after biochar production is among the many that have been investigated. By adding iron compounds, biochar's surface area is increased and new contact points are formed, improving its capacity for adsorption. Iron-biochars are valuable due to their exceptional ability to remove pollutants. Iron functionalized biochar prepared by post-pyrolysis surface Fe modification of plum stones. In this study, SEM-EDX analysis was performed to determine the surface morphology and elemental composition of plum stones biochar and FeCl3 impregnated biochar. After coprecipitation with Fe salt, Fe-BPS showed irregular structure with improved porosity. Content of iron significantly increased in Fe-BPS. Iron-based biochar's adsorption ability and catalytic activity work in concert to remove pollutants from wastewater via two mechanisms. Therefore, iron is added to the plum stone biochar to increase its adsorption capacity and reactivity, which makes it possible to remove a variety of organic and inorganic pollutants efficiently.
