Fluoride (F−) contamination in water is a global health concern, threatening the well-being of millions. This study investigated role ZnCl2/FeCl 3-rice husk-modified biochar (Zn-BC and Zn/Fe-BC) treating F−-contaminated surface groundwater under influence varying solution chemistry, co-existing ions, biochar-amended through column transport experiments. Modified showed maximum F− adsorption, 99.01% 91.90% using Zn/Fe-BC Zn-BC, respectively, than 85.87% raw (R-BC). Raw/modified biochars were characterized with FESEM-EDAX, FTIR, XRD, particle size, area, electro-kinetic potential, point zero charge analyses. Langmuir pseudo-second-order kinetic could explain that F−-biochar interactions are dominated by chemisorption at ambient temperature while physisorption higher temperatures. The salt concentrations co-occurring ions reduced sorption Zn/Fe-BC. Increased strengths led to electrophoretic mobility particles, i.e., biochar-biochar particles attract each other increase hydrodynamic diameter, which ultimately reduces active sites on for fluoride adsorption. Co-transport deposition saturated porous media revealed lower biochar, adsorption was observed 10 mM strength. Biochar governed electrostatic interactions, whereas mainly occurs chemisorption. In rural areas, hand pumps generally applied drinking cooking; thus, biochar-mediated sand columns can be utilized defluoridation. Thus, as potential bio-adsorbent natural optimum preparation treatment costs.

Biochar as a Soil Amendment for Restraining Greenhouse Gases Emission and Improving Soil Carbon Sink: Current Situation and Ways Forward

Sustainability, Journal Year: 2023, Volume and Issue: 15(2), P. 1206 - 1206

Published: Jan. 9, 2023

The global exponential rise in greenhouse gas (GHG) emissions over the last few decades has triggered an urgent need to contextualize low-cost and evergreen technologies for restraining GHG production enhancing soil carbon sink. GHGs can be mitigated via incorporating biochar into matrix sequestrate mineralized a stable form upon organic matter decomposition soil. However, efficiency of using offset from terrestrial ecosystems is still debatable. Moreover, literature, shows high functionality short-term laboratory studies, but it minimal or negative impacts field-scale experiments, leading conflicting results. This paper synthesizes information on ability mitigate dioxide (CO2), nitrous oxide (N2O), methane (CH4) biomass, with emphasis cropland soils. feedstock type, pyrolysis temperature, application rate factors showed significant effects controlling effectiveness emissions. Our study demonstrates that biochar, taken as whole, seen powerful easy-to-use tool halting rising tide Nonetheless, future research should focus (i) identifying other indirect related physicochemical characters (such pH/EH CaCO3 contents) may control (ii) fabricating aged biochars low nitrogen footprints, (iii) functionalizing biologically activated suppress CO2, CH4, N2O Overall, our paradoxical findings highlight functionalize modern capacity abate locking up their release carbonaceous lattice biochar.
