Abstract

Biochar, a carbon-rich material derived from biomass through thermochemical processes like pyrolysis and hydrothermal carbonization, has gained significant attention for its dual role in soil amendment and water remediation. This review examines recent advancements in biochar production, emphasizing the influence of feedstock types and process parameters on its physicochemical properties. Pyrolysis and hydrothermal carbonization yield biochars with distinct characteristics, ranging from high fixed carbon content for long-term carbon sequestration to enhanced nutrient retention capabilities. For soil applications, biochar improves fertility, water retention, and microbial activity, while reducing nutrient leaching and mitigating heavy metal toxicity. For water remediation, biochar's high porosity and functional groups make it effective in adsorbing heavy metals, pharmaceuticals, and dyes. Moreover, pretreatments like chemical activation can enhance its adsorption capacity, making biochar a versatile material for environmental remediation. This critical review correlates biochar properties with its environmental applications, highlighting optimization strategies for targeted uses.

生物炭在土壤修复和水修复中的应用综述

生物炭是一种从生物质中通过热化学过程如热解和水热炭化而获得的富碳物质，因其在土壤修复和水修复方面的双重作用而受到广泛关注。本文综述了生物炭生产的最新进展，重点介绍了原料类型和工艺参数对其理化性质的影响。热解和水热炭化产生的生物炭具有不同的特性，从高固定碳含量的长期固碳到增强的营养保留能力。对于土壤应用，生物炭可以提高肥力、保水能力和微生物活性，同时减少养分淋失和减轻重金属毒性。对于水的修复，生物炭的高孔隙率和官能团使其在吸附重金属、药物和染料方面效果显著。此外，化学活化等预处理可以增强其吸附能力，使生物炭成为一种多用途的环境修复材料。这篇重要的综述将生物炭的特性与其环境应用联系起来，重点介绍了针对目标用途的优化策略。

期刊介绍： The Journal of Analytical and Applied Pyrolysis (JAAP) is devoted to the publication of papers dealing with innovative applications of pyrolysis processes, the characterization of products related to pyrolysis reactions, and investigations of reaction mechanism. To be considered by JAAP, a manuscript should present significant progress in these topics. The novelty must be satisfactorily argued in the cover letter. A manuscript with a cover letter to the editor not addressing the novelty is likely to be rejected without review.
