Biochar-activated persulfate for organic contaminants removal: Efficiency, mechanisms and influencing factors

Peroxymonosulfate activation by tea residue biochar loaded with Fe3O4 for the degradation of tetracycline hydrochloride: performance and reaction mechanism

“…This result indicated that the method is suitable for a wide concentration range of TCH and could show a good removal effect, which was in good agreement with previous studies. 47 …”

The initial pH value of the research solution is also one of the most signicant factors that affect the degradation of TCH, 48 especially for reaction systems involving iron-based materials.…”

Biochar as a negative emission technology: A synthesis of field research on greenhouse gas emissions

“…enhancement of biological N-fixation in acidic soils (Ma, Egamberdieva, et al, 2019;Van Zwieten et al, 2015), ( 6) increase in crop yield (Farhangi-Abriz et al, 2021;Haque et al, 2019;Safaei et al, 2020), ( 7) alleviation of environmental pollution through soil and water remediation (Borchard et al, 2019;Li et al, 2020;Man et al, 2021), ( 8) restoration of degraded soils (Amoah-Antwi et al, 2020;Ghosh & Maiti, 2021;Rodriguez-Franco & Page-Dumroese, 2021), and (9) mitigation of climate change through GHG emission reduction and C sequestration in soils (Demir, 2020;Gupta et al, 2020: Purakayastha et al, 2021. A recent life cycle analysis has shown that C sequestration and GHG mitigation benefits of biochar overcompensate for CO 2 , N 2 O, and CH 4 emitted during biochar production (Matustik et al, 2020).…”

“…The term “biochar” has seen an exponential increase in use in the scientific literature over the last two decades (Figure 2), demonstrating increased interest of the scientific community on biochar for agricultural production and other purposes in several countries (Figure 3). This interest can be ascribed to reported beneficial impacts of biochar to: (1) long‐term sequestration of atmospheric CO 2 in soils (Purakayastha et al., 2021), (2) improvement in soil health (Alkharabsheh et al., 2021; Amoah‐Antwi et al., 2020; Darmawan et al., 2021) and fertility (Diatta et al., 2020; Mohawesh et al., 2021), (3) increase in soil water and nutrient retention (Are, 2019; Fischer et al., 2019; Razzaghi et al., 2020), (4) reduction in nitrogen (N) loss through leaching (Major et al., 2009), (5) enhancement of biological N‐fixation in acidic soils (Ma, Egamberdieva, et al., 2019; Van Zwieten et al., 2015), (6) increase in crop yield (Farhangi‐Abriz et al., 2021; Haque et al., 2019; Safaei et al., 2020), (7) alleviation of environmental pollution through soil and water remediation (Borchard et al., 2019; Li et al., 2020; Man et al., 2021), (8) restoration of degraded soils (Amoah‐Antwi et al., 2020; Ghosh & Maiti, 2021; Rodriguez‐Franco & Page‐Dumroese, 2021), and (9) mitigation of climate change through GHG emission reduction and C sequestration in soils (Demir, 2020; Gupta et al., 2020: Purakayastha et al., 2021).
