摘要: Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants renowned for their ubiquity in the environment and potential carcinogenicity. To verify compliance to European Drinking Water Directive (98/83/EC) Framework (2000/60/EC), these compounds have be monitored environmental waters. Conventional laboratory analysis implies important costs labour, may lead low sample representativeness due sampling, transport storage prior analysis. date, no portable equipment enables situ PAH determination with adequate selectivity sensitivity. build a cost-effective high-performance system, microfluidic device fast extraction of PAHs volume samples has been developed tested by solvent desorption. Pre-concentration recoveries were evaluated liquid chromatography associated multi-wavelength fluorescence detection (HPLC-FLD). The operational parameters optimised 5 µg L−1 spiked ...
