【摘要】：該文采用LC-MSMS/GC-MS/ICS聯(lián)合方法對(duì)含全氟辛酸(PFOA)模擬廢水及其氧化產(chǎn)物進(jìn)行了分析研究。結(jié)果表明LCMS-MS和ICS方法分別對(duì)PFOA及F-測(cè)定具有良好的線性關(guān)系,相關(guān)系數(shù)分別為0.999 3和0.999 9。PFOA在氧化降解過(guò)程中不僅有C—C鍵的斷裂,同時(shí)也有C—F鍵的斷裂,中間產(chǎn)物眾多,產(chǎn)物構(gòu)成較為復(fù)雜,其中主要為較短鏈的全氟和多氟化合物。由于短鏈全氟和多氟化合物常溫下以氣相形式存在,通過(guò)LC-MS-MS/GC-MS/ICS聯(lián)合分析方法對(duì)含PFOA廢水氧化降解過(guò)程中液相和氣相產(chǎn)物的綜合分析,可以更加客觀、全面反映PFOA在被氧化過(guò)程中的變化。
[Abstract]:The simulated wastewater containing perfluorooctanoic acid (PFOA) (PFOA) and its oxidation products were analyzed by LC-MSMS/GC-MS/ICS method. The results showed that the LCMS-MS and ICS methods had a good linear relationship for the determination of PFOA and F -, respectively. The correlation coefficients were 0.999 3 and 0.999 9.PFOA, respectively. At the same time, there are also C _ (F) bond breaks, there are many intermediate products, the composition of the products is more complex, among them, the short chain of perfluorinated and polyfluorinated compounds. Due to the existence of short-chain perfluorides and polyfluorides in gaseous form at room temperature, the comprehensive analysis of liquid phase and gas-phase products in the process of oxidation and degradation of wastewater containing PFOA can be more objective by means of LC-MS-MS/GC-MS/ICS joint analysis. The changes of PFOA in the oxidation process were fully reflected.
