The sorption of uranium and thorium from their aqueous solutions by using 8hydroxyquinoline modified Nabentonite (HQbentonite) was investigated by the batch technique. Nabentonite and HQbentonite were characterized by Xray fluorescence (XRF), Xray diffraction (XRD), scanning electron microscopy (SEM), and Fourier Transform Infrared (FTIR) spectroscopy.

When including uranium extracted from the oceans it becomes an inexhaustible source of energy. But in a molten salt reactor one can also use thorium as a fuel and it is estimated that there is a factor 3 more thorium on earth that uranium. Thorium is easily accessible and at this moment is mostly a byproduct of rareearth mining.

Uranium Mining and Milling Wastes: An Introduction

(99+ مراجعات العملاء)

Apart from the portion of the uranium removed, the sludge contains all the constituents of the ore. As long lived decay products such as thorium230 and radium226 are not removed, the sludge contains 85% of the initial radioactivity of the ore. Due to technical limitations, all of the uranium present in the ore can not be extracted.
