In this study, FeCl3, AlCl3, CaCl2, and kaolinite were selected as model soil minerals incubated with walnut shell derived biochar for 3 months the was then separated investigation of biochar-mineral interfacial behavior using XRD SEM-EDS. The XPS, TGA, H2O2 oxidation applied to evaluate effects interaction on stability biochar. Fe8O8(OH)8Cl1.35 AlCl3·6H2O newly formed surface or inside pores. At interface, organometallic complexes such Fe-O-C generated. All 4 enhanced resistance by...
Biochar is being recognized as a promising tool for long-term carbon sequestration, and biochar with high retention strong stability supposed to be explored that purpose. In this study, three minerals, including kaolin, calcite (CaCO3), calcium dihydrogen phosphate [Ca(H2PO4)2], were added rice straw feedstock at the ratio of 20% (w/w) formation through pyrolysis treatment, aiming improve stabilization in biochar. Kaolin CaCO3 had little effect on retention, whereas Ca(H2PO4)2 increased by...
Despite the vital roles of reactive radical species in coupled iron–carbon composite/persulfate (PS) system for eliminating pollutants, nonradical contributions are typically overlooked. Herein, we developed two efficient magnetic iron–char composites via low-temperature (BCFe-400) and high-temperature (BCFe-700) pyrolysis. The activated PS through pathways sulfamethoxazole (SMX) degradation. In BCFe-400/PS system, high-valent iron Fe(IV) was dominant active oxidation, evidenced by methyl...
Two phosphate fertilizers, triple superphosphate (TSP) and bone meal (BM), were premixed with sawdust switchgrass biomass for pyrolytic biochar formation. Carbon retention, P release kinetics, capacity of stabilizing heavy metals in soil evaluated. Results show that TSP BM pretreatment increased carbon retention from 53.5–55.0% to 68.4–74.7% 58.5–59.2%, respectively. The rate constants (k2) the TSP- BM-composite biochars are 0.0012–0.0024 0.89–0.91, respectively, being much lower than...
Pretreatment of biomass with phosphoric acid (HPO) for biochar production was expected to improve carbon (C) retention, porosity structure, and the sorption ability biochar. This study investigated interaction phosphorus C structure elucidate mechanisms by which HPO simultaneously captured created micropores. Sawdust soaked in diluted dried pyrolytic generation at 350, 500, 650°C. Results showed that pretreatment resulted 70 80% retention biochar, compared only about 50% remaining without...
Land application of animal manure often risks excessive phosphorus (P) release into the surrounding water. The aim this study was to convert dairy biochar, followed by their soil, and then investigate P from its derived biochar as well manure- biochar-amended soil. results showed that reduced when converted due formation less-soluble whitlockite [(Ca, Mg)(PO)]. cumulative released over 240 h 0.26 g kg, a 76% reduction (1.07 kg). kinetic determined fast desorption process better fitted...
Abstract Negative emissions technologies offer an important tool to limit the global warming <2 °C. Biochar is one of only a few such technologies, and at highest technology readiness level. Here we show that potassium as low-concentration additive in biochar production can increase biochar’s carbon sequestration potential; by up 45% this study. This translates estimated potential over 2.6 Gt CO 2 -C(eq) yr −1 , thus boosting efficiency utilisation limited biomass land resources,...
