    摘要： 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.

    摘要： The present invention relates to a process for separating at least one metal compound and/or a component thereof from a mixture, said process comprising contacting the said mixture with a heteropoly acid or heteropoly acid anion, thereby producing a precipitate comprising the heteropoly acid or heteropoly acid anion and the metal compound and/or a component thereof. The present invention further relates to a process for the purification of a mixture containing at least one metal compound, said process comprising contacting the said mixture with a heteropoly acid or heteropoly acid anion, thereby producing a precipitate that is substantially insoluble in the said reaction mixture and recovering the reaction mixture.

    摘要： Decribed are a process for the treatment of liquid residues from photographic processes, in which the residues are, where necessary after dilution, oxidized in stages with oxygen and ozone and where precipitated solids are, after pH value setting and the addition of auxiliary substances, separated by filtration from the oxidized residues, and a process for performing this process. In the new process, the residues to be treated are subjected to the following process stages:

    (a) oxygen oxidization,
    (b) oxygen-supported mild anodic oxidization and
    (c) a further complete anodic oxidization with current intensities higher than in (b),
    (d) in a manner known per se to an ozone treatment and in stage
    (e) the precipitated solids are separated in a manner known per se.
