The invention discloses a sampling-enriching method for atmospheric organic pollutants, and belongs to the technical field of analytical chemistry. According to the sampling-enriching method, atmospheric samples are collected through the unmanned aerial vehicle-mounted sampling-enriching device, when an unmanned aerial vehicle flies to a preset position, a sampling pump is remotely started for active sampling, and the samples are firstly enriched in real time through a cluster extractor; after sampling at the point is completed, the unmanned aerial vehicle flies to another preset position, meanwhile, the position of the cluster extractor loading cabin is automatically switched, the other extractor in the array cluster extractors is communicated with a sampling pump gas path, sampling and enrichment are conducted again, and after sampling is completed, the unmanned aerial vehicle returns to a test station or a laboratory for separation and analysis. According to the method, the problem that multi-point sampling cannot be carried out when the unmanned aerial vehicle carries on-line sampling equipment in one-time flight is solved, and the problems that sampling points are limited due to the fact that a sampling tank or a sampling bag carried by the unmanned aerial vehicle is large in size, and results are distorted due to adsorption or leakage of the samples in the transportation process are solved.

    本发明公开一种大气有机污染物的采样‑富集方法,属于分析化学技术领域。本发明的采样‑富集方法通过无人机载采样‑富集装置进行大气样品采集,当无人机飞行到预定位置时,遥控开启采样泵进行主动采样,样品首先经集束萃取器被实时富集;完成该点采样后,无人机飞到另一个预定位置,同时集束萃取器装载舱的位置自动切换,使阵列集束萃取器中另1支萃取器与采样泵气路连通,再次采样并富集,采样完成后返回测试站或实验室进行分离分析。该方法解决了无人机搭载在线采样设备一次飞行无法多点采样的问题,还解决了无人机搭载采样罐或采样袋因体积大使采样点位受限、以及在样品在运输过程中出现吸附或渗漏、造成结果失真的问题。
