Title: Preconcentration Of Metal Ions On Silica Gel Modified With 3(1-imidazolyl)propyl Groups
Author: Moreira J.C.
Gushikem Y.
Abstract: Silica gel functionalized with 3(1-imidazolyl)propyl groups and packed in a glass column is used to adsorb and preconcentrate metal ions from ethanol solution. Elution is done with 0.1 M hydrochloric acid in an ethanol/water mixture having a mole fraction of water of 0.85. The modified silica is applied to preconcentrate metal ions (Cu, Ni, Fe, Zn and Cd) from commercial ethanol, normally used as engine fuel. The method is suitable for quantifying these metals at low μg 1-1 levels. © 1985.
