WebThe main functional groups present on biochar surfaces are hydroxyl and carboxyl, which contribute to biochar's negative surface charges [51,61, 62]. The results from the FTIR … WebAbstract. A multi-technique analysis was performed on a range of biochar materials derived from secondary organic resources and aimed at sustainable recovery and re-use of wastewater phosphorus (P). Our purpose was to identify mechanisms of P capture in biochar and thereby inform its future optimisation as a sustainable P fertiliser. longview tx ss office
