RT other T1 Hollow fiber liquid phase micro-extraction for heavy metals speciation A1 López López, José Antonio A1 Moreno Aguilar, Carlos A1 Mendiguchía Martínez, Carolina A1 Pinto Ganfornina, Juan José A1 Mánuel Delgado, María Victoria A2 Química Analítica K1 Hollow fiber K1 Liquid phase micro-extraction K1 Metals K1 Speciation AB Metals appear at very low concentration level in natural waters. As a consequence, a sample treatment step before instrumental determination is often required; in which the metal has to be pre-concentrated and isolated from sample matrix components that interfere during instrumental analysis. Hollow fiber liquid phase micro-extraction appears as an alternative to traditional liquid extraction methods that allow obtaining higher pre-concentration factors and requires less amounts of solvents and reagents. Summarizing, HFLPME is a green alternative for sample treatment in the speciation of heavy metals.
