Development and Application of Portable In-situ Device for Determi-nation of Petroleum Contaminants in Water Based on Fluorescence Photometry
摘要
Abstract
An in-situ device based on fluorescence photometry for the determination of petroleum contaminants in water is developed.This device is designed as an immersion underwater probe to measure the concentration of petroleum pollutants in water based on the fluorescence intensity of aro-matic components in petroleum pollutants.The influence of optimal excitation wavelength and emis-sion wavelength and different excitation light sources on determination are investigated,and an inte-grated underwater detection optical path is designed.The results show that the in-situ oil measuring device has a good linear results(r2=0.999 1)in the concentration range of 0-20 mg/L oil in water.And the indication error of device is within 3%at concentration of 1 mg/L and 10 mg/L,the repeat-ability relative standard deviation(RSD)is 2.6%at concentration of 10 mg/L.The result determined by in-situ oil measurement device is highly consistent with laboratory measurement(n-hexane extrac-tion-fluorescence detection)(R=0.999 8).The recoveries of real samples are between 91.2%and 114%.This device does not require the use of organic solvent extraction and has good accuracy and stability,which can be applied to the rapid and in-situ detection of oil in water.关键词
