En savoir plus sur le livre
In this Book, new, cheap, simple and rapid methods have been introduced for the determination of different pollutants in water and food samples based on air-assisted liquid-liquid microextraction, magnetic solid-phase extraction, portable analytical instruments and digital image decomposition into the primary colors Red (R), Green (G) and Blue (B). Contents: A simple and rapid technique for the determination of copper based on air-assisted liquid-liquid microextraction and image colorimetric analysis Magnetic solid-phase extraction and a portable photocolourimeter using a multi-colour light emitting diode for on-site determination of nitrite Air-assisted liquid-liquid microextraction combined with flame atomic absorption spectrometry for determination of trace Pb in biological and aqueous samples Air-assisted liquid-liquid extraction coupled with dispersive liquid-liquid microextraction and a drying step for extraction and preconcentration of some phthalate esters from edible oils prior to their determination by GC
