Development of an Online-PFSPE-Spectrophotometry System for the Quantification of Environmental Pollutants

Abstract:

In order to detect the environmental pollutants in water sample with high sensitivity, an automatic method based on a combined preconcentration setup and flow injection system was developed. A novel packed fiber solid phase extraction (PFSPE) cartridge packed with electrospun nanofiber was first designed to adsorb environmental pollutants from water media in an online manner. Rhodamine B (RB) was selected as a model pollutant. Under the optimized conditions, a good linearity of wide range between 25-1000 ng mL^-1 was achieved. The LOD was 7.5 ng mL^-1. The method was applied to analysis RB in water samples with satisfactory results.
