Abstract
New ion exchangers have been recently synthesized at DEGUSSA by the polycondensation of suitable bifunctional silane monomers. Such ion exchangers can be obtained as spherical or egg-shaped particles with a grain size of about 0.1 to 1.5 mm and surface areas up to 700 m2/g. They are composed of a siliceous core and contain a high concentration of functional groups so that their exchange capacity is comparable to that of conventional organic systems. The functional groups are bound to the matrix via carbon-silicon bonds which are fairly stable towards hydrolysis (up to pH = 11 or 12). The main advantages of the new exchangers lie in the absence of swelling or shrinking during ion exchange operations, in their high thermal stability (up to 200 °C) and in the great variety of functional groups now available. The ion exchange properties of these exchangers have been investigated by studying the fixation of Ag(I) and Cu(I), As(III) and Sb(IIl), Bi(III), Cu(II) and Ni(II), Ga(III), Pd(II) and Pt(IV).
