Cold vapour generation electrothermal atomic absorption spectrometry and solid phase extraction based on a new nanosorbent for sensitive HG determination in environmental samples (sea water and river water)
Vereda-Alonso, Elisa Isabel; Siles-Cordero, Maria Teresa; López-Guerrero, María del Mar; García-de-Torres, Amparo; Cano-Pavón, José Manuel (2016-07-07)Mercury is not an essential element for plant or animal life and it is a potential environmental toxic because of its tendency to form covalent bonds with organic molecules and the high stability of the Hg-C bond. Reports ... -
Determination of Pb using F3eO4 GO join to DPTH for ferrofluid based dispersive solid phase extraction
