摘要：

New inorganic sorbents are obtained by modifying four different kieselguhrs and silica gel with 3-methyl-1-phenyl-pyrazolone-5 (HMPP). The products are characterized by elemental analysis and IR spectroscopy. The complexation ability of the sorbents with respect to some 3d elements such as Cu(II), Mn(II), Cd(II) and Pb(II) is investigated. The new sorbents are appropriate for simultaneous preconcentration of the above elements within a wide pH range.
