Abstract

Chlorinated organic pollutants constitute a significant category of persistent organic pollutants due to their widespread presence in the environment, which is primarily attributed to the expansion of agricultural and industrial activities. These pollutants are characterized by their persistence, potent toxicity, and capability for long-range dispersion, emphasizing the importance of their eradication to mitigate environmental pollution. While conventional methods for removing chlorinated organic pollutants encompass advanced oxidation, catalytic oxidation, and bioremediation, the utilization of biochar has emerged as a prominent green and efficacious method in recent years. Here we review biochar's role in remediating typical chlorinated organics, including polychlorinated biphenyls (PCBs), triclosan (TCS), trichloroethene (TCE), tetrachloroethylene (PCE), organochlorine pesticides (OCPs), and chlorobenzenes (CBs). We focus on the impact of biochar material properties on the adsorption mechanisms of chlorinated organics. This review highlights the use of biochar as a sustainable and eco-friendly method for removing chlorinated organic pollutants, especially when combined with biological or chemical strategies. Biochar facilitates electron transfer efficiency between microorganisms, promoting the growth of dechlorinating bacteria and mitigating the toxicity of chlorinated organics through adsorption. Furthermore, biochar can activate processes such as advanced oxidation or nano zero-valent iron, generating free radicals to decompose chlorinated organic compounds. We observe a broader application of biochar and bioprocesses for treating chlorinated organic pollutants in soil, reducing environmental impacts. Conversely, for water-based pollutants, integrating biochar with chemical methods proved more effective, leading to superior purification results. This review contributes to the theoretical and practical application of biochar for removing environmental chlorinated organic pollutants.

基于生物炭的复合材料用于去除氯化有机污染物:应用、机制和前景
氯化有机污染物是一类重要的持久性有机污染物,因为它们在环境中广泛存在,这主要归因于农业和工业活动的扩张。这些污染物的特点是具有持久性、剧毒性和远距离扩散能力,强调了消除这些污染物以减轻环境污染的重要性。去除氯化有机污染物的传统方法包括高级氧化法、催化氧化法和生物修复法,而生物炭的利用近年来已成为一种突出的绿色高效方法。在此,我们回顾了生物炭在修复典型氯化有机物方面的作用,包括多氯联苯(PCB)、三氯生(TCS)、三氯乙烯(TCE)、四氯乙烯(PCE)、有机氯农药(OCP)和氯苯(CB)。我们重点关注生物炭材料特性对氯化有机物吸附机制的影响。本综述强调了生物炭作为一种可持续和生态友好型方法在去除氯化有机污染物方面的应用,尤其是在与生物或化学策略相结合时。生物炭有助于提高微生物之间的电子传递效率,促进除氯细菌的生长,并通过吸附作用减轻氯化有机物的毒性。此外,生物炭还能激活高级氧化或纳米零价铁等过程,产生自由基以分解氯化有机化合物。我们观察到,生物炭和生物工艺在处理土壤中的氯化有机污染物方面有更广泛的应用,从而减少了对环境的影响。相反,对于水基污染物,生物炭与化学方法的结合被证明更为有效,可带来更优越的净化效果。本综述有助于生物炭在去除环境氯化有机污染物方面的理论和实际应用。
