WebIon exchange is a well established technique for the concentration and purifica-tion of uranium from sulphuric acid leach solupurifica-tions. The standard process usually involves adsorption of uranium on anion exchange resins contained in columns. Several types of resin are available: there are weak base resins and strong base resins in the ...

WebMany types of ion exchange resins have been tried for the separation of uranium [9–14]. Gawad [15] studied the adsorption behavior of uranium ions from nitrate solutions using the strong acid cation exchange Amberlite IR120 resin. The adsorption parameters have been optimized. The physical parameters WebUranium is widespread in nature and has been identified in many different minerals. It exists in several chemical oxidation states as well as a mixture of 3 radioisotopes. All naturally occurring isotopes of uranium are considered weakly radioactive, however, the principal health effects associated with uranium are due to its chemical toxicity. cyrtopholis bonhotei

Webconcentration of 22.7 g L-1 (0.64 M). The uranium mining industry has become heavily reliant on the use of strong base anion (SBA) exchange resins for the extraction of uranium. However, these conventional SBA resins are not compatible with the use of low quality waters, due to the suppression of ion WebThe cases outline typical sources of scandium and REE, such as streams of TiO 2 production, extracted phosphoric acid, barren uranium solutions and others.
