The thermal effect of electrokinetic remediation (EKR) is a kind of energy dissipation, which is an important part of the useless work in the process of EKR. Therefore, this study aims to reveal the phenomenon and mechanism of thermal effect and the energy distribution mechanism in the process of EKR. To explore the distribution mechanism of soil temperature during the EKR process, nine groups of orthogonal EKR experiments lasting 120 h were carried out. The experimental results show that the phenomenon of thermal effect is common in the process of electric remediation of uranium pollution, an...
