Abstract: The invention provides a method for the decontamination of a contaminated system, the method comprising at least the steps of: (a)selecting a decontaminating agent; (b)applying said decontaminating agent to said system; (c)collecting the used decontaminating agent; and (d)electrochemically treating the used decontaminating agent. Embodiments of the invention may further include at least one of an initial characterisation step, a chemical dosing step between steps (c) and (d), prior to electrochemical treatment of the used decontaminating agent, a subsequent characterisation step, wherein the system is re-evaluated in order to determine whether the decontamination objectives have been successfully accomplished, a UV-irradiation treatment, and a final step comprising post-treatment of the effluent remaining after the electrochemical treatment. The invention also envisages a method for the removal of contaminants from a process or environmental stream. The methods of the invention find particular application in the treatment of systems comprising radioactivity.
