生物炭的吸附特性及其在石油污染修复中的应用

Adsorption Characteristics of Biochar and Its Application in Remediation of Oil Polluted Environment

随着经济全球化的迅猛发展,人类对石油的需求与日俱增。石油及其产品会通过多种途径进入土壤、水体中,破坏生态系统并危害人体健康。生物炭的多孔结构和丰富的含氧官能团使其具有良好的吸附能力,加上其制取成本相对低廉且可回收利用,目前正逐渐应用于石油污染环境的修复中。本文介绍了生物炭的吸附特性及其吸附机理,对生物炭在石油污染土壤和水环境中的应用进行了综述。

With the rapid development of economic globalization,the demand for oil has been increasing.Petroleum or its products enter the soil and water bodies in various ways,destroying ecosystems and even endangering human health.The porous structure and rich oxygen-containing functional groups of biochar make it has good adsorption ability.In addition,the production cost of biochar is relatively low,and it can be recycled and reused.It is currently being used in petroleum pollution remediation.The adsorption characteristics and mechanism of biochar are introduced,and the application of biochar to remediate oil polluted soil and water environment are reviewed in the paper.
