關(guān)鍵詞:全氟化合物; 全氟辛酸; 全氟辛烷磺酸; 持久性有機污染物

摘要:全氟化合物（Perfluorinated compounds，PFCs）是一類新型有機污染物，由于具有環(huán)境污染持久性、遠距離運輸性和生物毒性等，近年來受到廣泛關(guān)注。為了更好地應對PFCs所帶來的環(huán)境風險，總結(jié)了PFCs中應用最為廣泛的全氟辛酸（Perfluorooctanoate，PFOA）和全氟辛烷磺酸（Perfluorooctane sulfonate，PFOS）在水環(huán)境中的污染現(xiàn)狀。同時較為全面地介紹了目前PFOA與PFOS的處理技術(shù)及其原理和優(yōu)缺點。根據(jù)實驗數(shù)據(jù)的分析，推薦使用離子交換樹脂去除ng/L級別的PFOS。目前微生物法尚不成熟，盡管吸附法和氧化法去除率較高，在TiO2/VUV（pH=4）的體系中PFOA的降解率和脫氟率分別達到了98.3%和52.4%，但仍存在脫氟率較低的問題。如何提高脫氟率也是未來的一個研究方向，制定檢測、管控相關(guān)的法律政策和開發(fā)易降解的替代品是控制PFCs污染的關(guān)鍵。
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.
