| 摘 要： | 利用聚丙烯无纺布（polypropylene non-woven fabric，PP NWF）和耗氧传感器结合来构建一个乳化油监测探头。PP NWF是一种超疏水吸油材料，可以快速吸附乳化油污，利用该性能，本监测探头先用PP NWF富集乳化油污，再用探头对材料中的氧含量进行监测，从而达到乳化油监测的目的。本文通过监测不同种类的乳化油（表面活性剂为吐温80的正己烷乳化油、石油醚乳化油、甲苯乳化油及表面活性剂为司班80的正己烷乳化油、石油醚乳化油、甲苯乳化油）来验证其可行性。结果表明：该监测探头可以监测到不同乳化条件下的乳化油，并且能监测到不同种类的乳化油。其中监测甲苯乳化油时响应时间最短，可以在6s内监测到该油污。固定PP NWF时的耗氧传感器探头的最低检测限为1.27g/L，监测效率较未固定PP NWF时提高了近8倍。综上，固定PP NWF的耗氧传感器探头可以作为海洋乳化油监测重要的一个系统，对海洋乳化油泄漏事故进行在线实时监测，可以快速准确提供早期溢油预警。

| Abstract: | An on-site marine oil spillage monitoring probe is developed by combining oxygen consumption sensor with polypropylene non-woven (PP NWF). PP NWF is a hydrophobic/oleophilic material which can absorb emulsified oil quickly. To enhance the monitoring efficiency, the spilled emulsified oils were first enriched by PP NWF absorption, then detected by the change of the oxygen content in the porous space of PP NWF. With PP NWF, the probe has shown close to 8 times less Reliable Low Detection Limit (RLDL) in detecting emulsified n-hexane oil spillage. It is demonstrated that the monitoring probe can effectively detect various kinds of emulsified oils, including n-hexane, petroleum ether and toluene, emulsified by different surfactants, such as Tween-80 or Span-80. The impact of surfactants on the response time and sensitivity of the probe in monitoring different types of spilled oils were systematically studied. With the rapid response time and high noise-to-signal ratios, the probe may be used as a key component in marine oil spillage monitoring systems to provide early stage pollution warning. |
