The Jiangmen Underground Neutrino Observatory (JUNO) uses 20k tons of liquid scintillator (LS) to detect neutrinos. The content of radioactive substances in the liquid scintillator will affect the experimental results. JUNO will use counter current water extraction to reduce the radioactive metal ions inside the LS. In this article, The factors that affect the final water extraction like the partition coefficient and the factors that affect it, the optimal mass transfer droplet size, the flow… Expand
