Abstract


General principles for the selection of conditions and modes of electrochemical decontamination of different construction materials are formulated. The most suitable conditions for the electrochemical decontamination are those which are accompanied by surface polishing. The electrochemical polishing improves the surface properties during decontamination. Compositions based on the system H2SO4–H3PO4–H2O are recommended as basic solutions for decontamination of a wide range of construction materials. In comparison with the stationary electrochemical decontamination mode, external electrode mode has significant advantages and provides essential reduction of specific reagent and electricity consumption. A fundamentally new design of external electrode is proposed.

Keywords
