Abstract
The performance of silica gel, modified by the impregnation with a high molecular weightquaternary amine (triethyl octadecyl ammonium iodide), used for the concentration of heavy metals
occurring in water is studied. The material under study captures Cd, Pb, which are capable of forming
stable complexes with I - ions.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.
