New amino-inorganic hybrids from talc silylation and copper adsorption properties

摘要

The aminated trialkoxysilanes were immobilized on natural talc mineral surface. The obtained inorganic-organic hybrids, designated as TC_x(x = 1 to 3) are related to 3-aminopropy1-,N- propylethylenediamine-and N-propyltriethylenedeaminetrimethoxysilane, respectively. The number of amino groups attached to the pendant organic chains were 4.38, 2.56 and 2.03 mmol g~-1 for TC_x (x-1 to 3), respectively.
