A fast and green approach for the non-chromatographic assaying of volatile metalorganic compounds (VMOCs) is presented, involving the use of thermal desorption microwave-induced plasma optical emission spectrometry for the multi-species simultaneous determination of VMOCs in wastewater plant samples after headspace solid-phase microextraction (HSSPME-TD-MIP-OES), and optimized as a tool for the assessment of ambient exposure to hazardous VMOC pollutants. With the aim of VMOC monitoring, all species are separated and quantified within 10 s in comparison with about 10-20 min required by conventional GC-based procedures. Calibration against aqueous standards was carried out for several metalorganic species. The method was successfully applied for the quantitative extraction of As, Bi, Hg, Sb, Si and Sn compounds. Limits of detection ranging from 5 to 30 ng L and relative standard deviations lower than 4% were obtained. The method is appropriate for high-sample-throughput measurements, and it proved to be suitable for the analysis of wastewater and sewage sludge samples.
本文提出了一种快速、绿色的非色谱法测定挥发性金属有机化合物（VMOCs）的方法，该方法采用热解吸微波诱导等离子体光发射光谱法，在顶空固相微萃取（HSSPME-TD-MIP-OES）后对污水处理厂样品中的VMOCs进行多物种同时测定，并优化为评估环境中有害VMOC污染物暴露的工具。为了监测VMOCs，与传统的基于气相色谱的方法所需的约10-20分钟相比，所有物种在10秒内即可分离和定量。对几种金属有机物种进行了针对水溶液标准品的校准。该方法成功应用于砷、铋、汞、锑、硅和锡化合物的定量萃取。获得了5至30 ng/L的检测限和低于4%的相对标准偏差。该方法适用于高通量样品测量，并且被证明适用于废水和污水污泥样品的分析。
