摘要:
全氟化合物（Perfluorinated compounds，PFCs）是一类新型有机污染物，由于具有环境污染持久性、远距离运输性和生物毒性等，近年来受到广泛关注。为了更好地应对PFCs所带来的环境风险，总结了PFCs中应用最为广泛的全氟辛酸（Perfluorooctanoate，PFOA）和全氟辛烷磺酸（Perfluorooctane sulfonate，PFOS）在水环境中的污染现状。同时较为全面地介绍了目前PFOA与PFOS的处理技术及其原理和优缺点。根据实验数据的分析，推荐使用离子交换树脂去除ng/L级别的PFOS。目前微生物法尚不成熟，尽管吸附法和氧化法去除率较高，在TiO2/VUV（pH=4）的体系中PFOA的降解率和脱氟率分别达到了98.3%和52.4%，但仍存在脱氟率较低的问题。如何提高脱氟率也是未来的一个研究方向，制定检测、管控相关的法律政策和开发易降解的替代品是控制PFCs污染的关键。
Abstract:
As a type of emerging organic pollutants, perfluorinated compounds (PFCs) have been widely concerned in recent years due to their long-term environmental pollution, long-distance transportation and biological toxicity. To deal with the environmental risks caused by PFCs, the pollution situation in water environment of the two most widely used PFCs: Perfluorooctanoate (PFOA) and Perfluorooctane sulfonate (PFOS) were comprehensively summarized. In addition, the treatment technology and its mechanism, advantages and disadvantages of PFOA and PFOS were discussed. According to the analysis of experimental data, ion exchange resin can be recommended for the removal of ng/L PFOS. At present, microbiological methods are not yet mature. Although the removal rates of adsorption and oxidation treatment technologies are higher, the degradation rate and defluorination rate of PFOA in the TiO2/VUV (pH=4) system can reach 98.3% and 52.4%, respectively. The defluorination rate is relatively low. Improving the defluorination rate has become a new research point in the future. Formulating detection and control laws and developing degradable substitutes are key points to control PFCs pollution.
