Study on high-sensitivity detection system of aromatic hydrocarbons

Abstract

In order to meet the requirement of oil pollution detecting, a study on the detection system of oil in water is initiated in this paper. According to the fluorescence characteristics of aromatic hydrocarbons in oil, an optical system is made to produce UV and to detect fluorescence, and then we use a PMT to collect the fluorescence and transform it into current signal, which can be processed by the system composed of hardware and software. We take C8051F020 MCU as the core of hardware; also the system can complete the data acquisition, storage, and communicate with PC via interface software. After implementation of software, we take experiments to test the effectiveness of system. Experimental results show that whole system performed well in detection of aromatic hydrocarbons. © 2012 Springer-Verlag Berlin Heidelberg.
