Luiza N.H. Arakaki scite author profile

published as an Advance Article on the web 4th February 2002Ethyleneimine (etn) has been covalently bonded onto silica gel via homogeneous (SiSN1) and heterogeneous (SiSN2) routes. Both synthesised silica gel surfaces have been applied to adsorb divalent cations from aqueous solution at room temperature. The series of isotherms of adsorption were adjusted to a modified Langmuir equation, after collecting the data from the solid/MCl 2 solution (M = Co, Ni, Cu, Pb and Hg) interfaces. The maximum adsorption were 1.
