| Summary: | (Cr3+). Electrochemistry has proven to be a valuable tool. and radioactivity) . According to 40 CFR 261, if a process in any step creates chromate, the final waste has to be tested besides converting the chromate completely, also decreases chromate (Cr 6+), which makes it a mixed waste problem (Cr 6+ concept, the chromate (Cr6+) ions are being reduced. This is done by the use of an electrochemical cell (reactor bed). electrochemical process for decontamination of components in a toxicity characteristic leachate procedure. In order to industry. Ion exchange was also studied as an alternative makes the test cell feasible to scale up and use in the method of reducing chromate. However, the ion exchange One of ABB Atom's methods under development, ELDECON, is an pass the test, the chromate have to be reduced to chromium reduce and exchange the chromate ions. relationship to reduce varying amounts of solution. This resins investigated were not efficient enough to effectively species while producing small amounts of waste. However, the The method involves ferric nitrate as a reagent, which the reaction time. The experiment showed a linear used in nuclear power plants. ELDECON removes radioactive waste sludge that is produced in the ELDECON process contains When incorporating indirect electrolysis into the ELDECON |
