SOME ASPECTS CONCERNING THE INTERACTION BETWEEN URANIUM AND ETS-10 TITANOSILICATE1
The present study reports the U(VI) uptake from solution on ETS-10 (Engelhard Titanium Silicate No. 10) and its modification achieved by post-synthesis treatment. The experiments were performed in the same conditions previously reported, in order to compare the influence of the mesoporosity in the large-size uranyl ion (UO22+) uptake. The results were evaluated using a Lagergren first order equation and the apparent thermodynamic parameters of the uranium uptake onto the considered materials were calculated.
