We have been carried out studies of low-temperature plasma electrolysis (LTPE) action on water and water solutions of different classes of inorganic and organic compounds. The formation of liquid bipolar bifunctional electrode is basis of faraday processes. This fact is difference of LTPE and classic electrolysis. We have carried out studies on the use of LTPE for the purification of industrial wastewater from inorganic heavy metal salts and radioisotopes. It has been considered the opportunity of LTPE application during the heavy metal salts and trans-uranium and trans-plutonium compounds extraction. The dependence of degree of the purification from initial concentrations of radioactive elements and the number of recycles during processing of liquid in continuous reactor was examined. It has been determined the relative contribution of filtration of the solutions made of nature waters in whole effect of liquid environments purification from trans-uranium elements during the LTPE. Purification degree was shown to depend on particles aggregation time and their subsequent separation by filtration (Fig. 1). For Sr purification degree may be 80% and higher, whereas Cs was shown to be detained slightly on filters during electrolysis (Fig. 2). 105 Fig. 1. The purification degree of aqueous solutions of radioactive isotopes: 1 – 5 – recycle coefficient. Fig. 2. The effect of LTPE on Sr and Cs extraction. It has been showed high effectiveness of low-temperature plasma electrolysis method in extraction of heavy metal salts and radioisotopes from aqueous solutions.
