Rare-earth (RE) industries generate a massive amount of radioactive residue containing high thoriumconcentrations. Due to the fact that thorium is considered a non-economic element, large volume ofthese RE processed residues are commonly disposed of without treatment. It is essential to study anappropriate treatment that could reduce the volume of waste for final disposition. To this end, thisresearch investigates the applicability of carbon-based adsorbent in separating thorium from aqueousphase sulphate is obtained from the cracking and leaching process of solid rare-earth by-product residue.
Adsorption of thorium from the aqueous phase sulphate by carbon-based electrodes was investigatedthrough electrosorption experiments conducted at a duration of 180 minutes with a positive potentialvariable range of þ0.2V to þ0.6V (vs. Ag/AgCl). Through this research, the specific capacity obtained wasequivalent to 1.0 to 5.14 mg-Th/g-Carbon. Furthermore, electrosorption of thorium ions from aqueousphase sulphate is found to be most favorable at a higher positive potential of þ0.6V (vs. Ag/AgCl). Thisstudy's findings elucidate the removal of thorium from the rare-earth residue by carbon-based electrodesand simultaneously its potential to reduce disposal waste of untreated residue.
