  • 摘要: 将通过水热合成法制备的金属有机骨架材料[MIL-101（Cr）]作为吸附剂应用于吸附环境水样中的亚硝胺类消毒副产物，采用超高效液相色谱-串联质谱法（UHPLC-MS/MS）进行测定.通过SEM、TEM和FT-IR技术对MIL-101（Cr）的表面形态和特征基团进行表征，并对影响萃取效率的主要因素，如MIL-101（Cr）的用量、萃取时间、水样的pH值和解吸条件等进行考察.研究表明，当MIL-101（Cr）用量为6.0 mg，pH=9.0，30℃下9 min内可达吸附平衡，回收率高于63.5%，3种亚硝胺的检出限为0.029-0.283 μg·L-1.将方法应用于环境水样的测定，加标回收率在77.9%-107.2%范围内，相对标准偏差低于5.4%.该方法操作简单快速、准确可靠、检出限低，可用于水样中痕量亚硝胺类消毒副产物的检测.
    Abstract: The metal-organic frameworks[MIL-101(Cr)] was synthesized by hydrothermal method and applied to the absorption of N-nitrosamines (NAs) in environmental water coupled with ultra high performance liquid chromatography-tandem mass spectrometry(UHPLC-MS/MS). The surface morphology was characterized by SEM, TEM and FT-IR. The experimental parameters of solid phase extraction were investigated including the amount of MIL-101(Cr), extraction time, sample pH and desorption conditions. The recoveries of NAs were over 63.5% within 9.0 min when the mass concentration of MIL-101(Cr) was 6.0 mg, the pH value of water sample was 9.0, the desorption temperature was 30℃. The detection limits were in the range of 0.029-0.238 μg·L-1. The developed method was successfully applied to the analysis of NAs in environmental water samples, the recoveries were in the range from 77.9% to 107.2% and the RSDs was within 5.4%. The proposed method was simple, rapid and accurate, which could be applied to the analysis of the trace amount NAs in environmental water samples.
