Abstract

Persistent pollutants cause adverse effects to human and environmental health. Most polychlorinated biphenyls (PCB) and polycyclic aromatic hydrocarbons (PAH) are toxic and stable in the environment, yet their removal is rarely targeted by conventional remediation methods. Alternatively, nanotechnology appears promising for contaminant removal. Indeed, nanomaterials have unique size-dependent properties due to their high specific surface area. Nanomaterials also possess fast dissolution properties, strong sorption, supermagnetic characteristics and quantum confinement. This manuscript reviews the application of nanotechnologies for the removal of PCB and PAH from contaminated water sources.

纳米技术从水中去除多氯联苯和多环芳烃的研究进展

摘要

持久性污染物会对人类和环境健康造成不利影响。大多数多氯联苯（PCB）和多环芳烃（PAH）在环境中均具有毒性和稳定性，但传统的修复方法很少将其去除。另外，纳米技术似乎有望去除污染物。实际上，纳米材料由于其高的比表面积而具有独特的尺寸依赖性。纳米材料还具有快速溶解特性，强吸附性，超磁特性和量子限制。该手稿回顾了纳米技术在从污染水源中去除PCB和PAH的应用。
