摘要：

The ion-exchange-precipitation mechanism of sorption was established for amorphous spherically granulated titanium phosphates. Under optimal conditions (pH 5.0-6.0) uranium undergoes sorptive accumulation in amounts substantially exceeding the ion-exchange capacity of the sorbents. Under acidic and alkaline conditions, where ion exchange cannot proceed, uranium sorption follows the precipitation mechanism, which allows treatment of real uranium-containing solutions without optimized conditions. The ion-exchange-precipitation mechanism also operates in sorption of some heavy metals on amorphous spherically granulated titanium phosphates.
