Abstract Biochar is a widely known soil amendment. Here we synthesize the available information on influence of biochar application different properties and crop productivity using meta-analysis. Global data applications physical, chemical, microbial properties, were extracted from literature statistically analyzed. Based selection criteria, 59 studies published between 2012 2021 selected for Correlations developed effect size productivity. Application increased pH, cation exchange capacity, organic carbon by 46%, 20%, 27%, respectively, with greater effects in coarse fine-textured soils. Effects chemical variable among prepared feedstocks. Among physical reduced bulk densities 29% porosity 59%. at higher pyrolytic temperatures (> 500 ℃) improved density to extents (31% 66%, respectively). lower (< had diversity (both bacterial fungal), more diverse populations medium textured soils, while fungal fine only soil. The was correlated responses meta-analysis highlighted need conduct long-term field experiments provide better explanations changes as it undergoes aging, its longer-term timing re-application biochars.

Biomass-Based Adsorbents for Removal of Dyes From Wastewater: A Review

Frontiers in Environmental Science, Год журнала: 2021, Номер 9

Опубликована: Дек. 9, 2021

Dyes, especially azo dyes contained in wastewaters released from textile, pigment, and leather industries, are entering into natural waterbodies. This results environmental deterioration serious health damages (for example carcinogenicity mutagenesis) through food chains. Physiochemical, membrane processes, electrochemical technology, advanced oxidation reverse osmosis, ion exchange, electrodialysis, electrolysis, adsorption techniques commonly used conventional treatment technologies. However, the limitations of most these methods include generation toxic sludge, high operational maintenance costs. Thus, technological advancements use to remediate effluents. Adsorption using nonconventional biomass-based sorbents is greatest attractive alternatives because their low cost, sustainability, availability, eco-friendly. We present reviewed up-to-date publications on for dye removal. Conceptualization synthesizing state-of-the-art knowledge characteristics, experimental conditions were also discussed. The merits various biosorbents reflected. maximum capacities synthesized order biomass type (algae, agricultural, fungal, bacterial, activated carbon, yeast, others). Surface chemistry, pH, initial concentration, temperature, contact time, adsorbent dose as well ways preparations materials affect biosorption process. Based average capacity, those arranged prioritized. best fit isotherms Freundlich Langmuir models) basic operating parameters removal retrieved. Which adsorbents have greater potential based uptake nature, cost-effectiveness, bulk mono multilayer behavior was including desorption cycles preparation operation implementation this technology forwarded.
