Nitrogen compounds like ammonia and nitrite can antagonistically affect the environment human health in many ways. The high rise demand for food has led to excessive use of fertilisers eventually causing increased losses reactive nitrogen environment. Ammonia be introduced into through agricultural runoff, wastewater discharges other anthropogenic activities. over-accumulation different forms (ammonia nitrite) ecosystem noxious life including humans aquatic life. High concentrations both nitrogenous nutrient pollution, decreased oxygen levels water bodies ultimately resulting dead zones eutrophication. In elevated cause methemoglobinemia. Remediation these contaminants become a crucial environmental concern recent past. To prevent pollution reduce their harmful effects several mechanisms physical chemical treatments have been it is also required fix remaining pollutants by biological agents. Current review deals with mechanism, organisms, enzymes involved transformation fixation various (fixation using chemicals, modified biochar, solidification, phytostabilisation, nano material-related compounds, etc.)

Synergistically enhancing nitrate reduction into N2 in water by N-doped Pd–Cu biochar bimetallic single-atom electrocatalysis

Biochar, Journal Year: 2024, Volume and Issue: 6(1)

Published: Jan. 15, 2024

Abstract Noble metal materials have been identified as high efficiency catalysts for electrocatalytic reduction of nitrate, and the synthesis manufacture catalytic activity environmentally friendly activating hydrogen water purification applications is extremely attractive. In this work, Pd–Cu single-atom (Pd–Cu-N-BC) were first prepared by direct growth on bamboo biochar regulating concentration precursors doping method, then enhanced nitrate performance N 2 generation. The results showed that Pd–Cu-N-BC displayed excellent reusability in with a low potential 0.47 V vs. RHE (@10 mA cm −2 ). maximum removal generation could reach about 100% 72.32% within 180 min, respectively. density functional theory (DFT) calculations confirmed Cu atoms catalyze electrochemical to nitrite, Pd anchored nitrogen-doped (N-BC) lattice nitrite involving formation radical (H*). characterization XANES electronic synergistic effect between single significantly promotes production through hydrogenation while inhibiting byproducts, leading . Finally, was designed 3D particle electrode exhibiting stability reusability, which be considered suitable candidate remediation contamination. Graphical

Hydraulic characteristics and vegetation performance of the Yellow River sediment modified by biochar

Biogeotechnics, Journal Year: 2024, Volume and Issue: 2(2), P. 100070 - 100070

Published: Jan. 15, 2024

The Yellow River sediment (YRS) is an important potential soil resource for the mine land reclamation and ecological restoration in arid regions of northern China. However, it has shortcomings poor water-holding capacity needs to be modified urgently. Therefore, two types biochar, namely rice husk biochar (RHB) coconut shell (CSB), were utilized this study modify YRS compared with ash (RHA). Some engineering properties (MYRS), including pore structure, water retention, permeability, vegetation performance, investigated by considering effects dosages. Results showed that addition three materials decreased bulk density increased volume extremely micro (d<0.3μm), as well effective porosity capillary porosity, thus contributed increase sediment. Among conditioners, RHB optimal choice improving YRS. Furthermore, effect becomes more pronounced increasing application rates. With materials, permeability coefficients MYRS gradually decreased, while retention rate during evaporation significantly increased. pot experiment conditioners all had significant promoting on growth oats. In particular, plain soil, total biomass oats grown 21 days 17.46%, 32.14%, 49.60% after adding 2%, 4%, 8% RHB, respectively. This introduces a new approach using planting semi-arid areas China facilitate restoration.

Biochar application regulating soil inorganic nitrogen and organic carbon content in cropland in the Central Europe: a seven-year field study

Biochar, Journal Year: 2024, Volume and Issue: 6(1)

Abstract Biochar incorporation into soil has shown potential, in enhancing nitrogen fertilizer (N-fertilizer) efficacy and organic carbon content (SOC). This study addresses a critical gap the literature by investigating effects of biochar addition over seven-year period (2014–2020) on inorganic N, SOC, pH Haplic Luvisol. The research involved rain-fed field experiment, with crop rotation comprising spring barley, maize, wheat, pea. Biochar, applied at rates 0, 10, 20 t ha −1 2014, was reapplied to specific plots 2018. also combined N-fertilizer three level (N0, N1, N2). Results showed significant interactive influence combination NO 3 − NH 4 + contents. Intriguingly, 10 consistently decreased N levels across most examined months. Increasing application led rise pH, establishing clear, negative correlation between content. significantly increased SOC compared control, particularly after reapplication However, this effect diminishing trend time. suggests that incorporating treatments may enhance effectiveness. long-term implications mineralization are individual combinations. Except N2 2019, did not affect yields. Studied properties, including those influenced had nuanced impact different aspects yield. Graphical
