摘要：
Herein, we have used mesoporous Al(2)O(3)as adsorbent and compared its efficacy with chromatographic neutral alumina for the selective adsorption and separation of Th(IV). The metal ions form complex with thorin and the Th-thorin complex gets selectively adsorbed on the mesoporous alumina at pH 1 unlike other metal ions. The R(2)value of Langmuir isotherm model was found to be the highest and closer to 1. The adsorption capacities at 283, 303 and 328 K were found to be 50, 51.02 and 51.81 mu molg(-1)respectively. The adsorbed thorium was desorbed from the adsorber upon treatment with trisodium citrate.
