化学传感器阵列(由8种导电聚合物组成)用于连续监测在线流动池产生的废水顶空中工业污染物的存在或不存在。在一个生活废水(克兰菲尔德大学污水处理厂)中加入柴油，以刺激废水进水口出现间歇排放。传感器之间的响应模式被用来检测废水中有机化合物的存在。传感器响应模式或指纹之间的相关性也使用主成分分析进行了分析。结果清楚地表明，化学传感器阵列可以快速识别废水基质中有机化合物(如柴油)的存在，并可进一步开发用于监测污水厂入口处的工业污染物。(C)2002爱思唯尔科学有限公司。保留所有权利。
A chemical sensor array (consisting of 8 conducting polymers) was used to continuously monitor for the presence or absence of industrial pollutants in the headspace of wastewater generated from an on-line flow-cell. A domestic wastewater (Cranfield University sewage works) was dosed with diesel to stimulate the presence of an intermittent discharge in a wastewater influent. Response patterns between the sensors were used to detect for the presence of organic compounds in the wastewater. Correlations between the sensor response patterns or fingerprints were also analysed using principal component analysis. The results clearly demonstrate that a chemical sensor array can rapidly identify the presence of organic compounds (such as diesel) in a wastewater matrix and could be further developed to monitor for industrial pollutants at the inlet of a sewage works.
