Use of modified silica gel for concentrating Pb (II) and Cd (II) occurring in form of complex anions.

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 metalsoccurring in water is studied. The material under study captures Cd, Pb, which are capable of formingstable complex...
