Sample preparation is the most expensive step in the analytical procedure, and can introduce substantial systematic and non-systematic errors. In gen…
The occurrence of organic (e.g., agrochemicals, aromatics, polychlorinated biphenyls) and inorganic (e.g., Cd, Pb, Hg, As) pollutants in the environment has stimulated the need to monitor the levels of these species in order to promote the environmental and food safeties. Solid phase extraction (SPE) methods are the most used strategy for sample preparation for the analysis of these pollu…
