ecletica-361	Déniz, Rubén del Toro; Echevarría, Marlene Seijo; Terra, Zaida Fernández; Espinosa, Ana María Peón; de Moya, Humberto Varela	Use of modified silica gel for concentrating Pb (II) and Cd (II) occurring in form of complex anions	2007	4	.pdf	application/pdf	1758	77	60	The results obtained about the metal capture, under dynamic conditions, are described and metal ions are removed by desorption with EDTA and quantified by AAS. The determination of such metal species was done, during filtration, by means of atomic absorption spectrophotometry at a wavelength of 283.3 nm for Pb and 228.3 nm for Cd in a Karl Zeiss AAS-3 spectrophotometer.	cache/ecletica-361.pdf	txt/ecletica-361.txt
