摘要

土地的密集使用导致土壤退化和污染,引起人们对粮食安全和环境健康的担忧。重金属污染土壤的修复已成为一项严峻的全球性挑战。由有机生物质水热碳化产生的水包炭具有固碳、减少温室气体排放和改良土壤的潜力,有望成为一种土壤改良剂。许多研究都调查了水炭在改善土壤物理特性和固定重金属能力方面的应用效果。本研究旨在分析文献中关于碳化温度、原料、土壤质地、土壤用途类型和土壤 pH 值等各种因素如何影响水碳吸附重金属的数据。通过对现有研究的综合分析,本元分析深入探讨了水炭作为重金属污染土壤可持续修复解决方案的潜力。

Hydrochar as an adsorbent for heavy metals in soil: A meta-analysis

The intensive land use has led to soil degradation and contamination, resulting in concerns about food security and environmental health. Remediation of heavy metal-contaminated soils has become a critical global challenge. Hydrochar, derived from the hydrothermal carbonization of organic biomass, shows promise as a soil amendment due to its potential for carbon sequestration, greenhouse gas reduction, and soil improvement. Numerous studies have investigated hydrochar's application effects on improving the soil's physical properties and ability to immobilize heavy metals. This study aims to analyze data from the literature on how various factors, such as carbonization temperature, feedstock, soil texture, soil use type, and soil pH, affect heavy metal adsorption by hydrochars. By synthesizing existing research, this meta-analysis provides insights into the potential of hydrochar as a sustainable remediation solution for heavy metal-contaminated soils.
