Photochemical sample treatment: a greener approach to chlorobenzene determination in sediments

Abstract

Due To worker's exposure,solvent and stationary phases'consumption,sample purification is one of the most polluting steps in analytical procedures for determination of organic pollutants in real samples.The use of photochemical sample treatment represents a valid alternativ emethodology for extracts cleanup allowing for a reduction of the used amount of organic solvents. In this paper we report the first application on the photolytic destruction of organic substances to eliminate some of the interferences in the analysis of Chlorobenzenes in sedimentsamples. The method'sefficiency and robustness werecompared with classics column purification process currently used in cleanup procedures in sediment analysis.Quality parameters such as recovery, linearity and reproducibility were studied.The entire procedure was validated by three replicate analysis of spiked real sediment sample......
