Removal of Thorium from industrial waste via electrosorption technique

Abstract

Abstract Activated carbon electrode has been tested as a potential sorbent for removal of Th ions from the actual wastewater sampel by electrosorption technique. The objective of this research is to investigate the performance of activated carbon electrode for remediation of real thorium sample. Adsorption of thorium ion by activated carbon electrodes was investigated with contact time up to 180 minutes by using positive potential at 0.2V (vs. Ag/AgCl), 0.4V (vs. Ag/AgCl) and 0.6v (vs. Ag/AgCl). Result shows that the condition has the highest percentage of thorium ion removal is at 0.6V (vs. Ag/AgCl) with highest specific capacity at 0.5 mg Th/g Carbon. Based on this research, the removal of thorium through electrosorption technique has the tendency to remove thorium ion and parameter such as contact time of electrosorption and voltage applied should be studied in more depth, where the removal of thorium is expected to increase.
