  1. NEW COMPOSITE MATERIALS FOR DECREASING OF RADIOACTIVE MOLECULAR IODINE IN THE WATER COOLANT ON THE WORKING AND NEW DEVELOPED NPPs. Prof. Sergey A. Kulyukhin Dr. Lubov' V. Mizina Eng. Anna A. Tishina Institute of Physical Chemistry and Electrochemistry Russian Academy of Sciences Moscow, Russia

  2. I-, IO3-, I2, CH3I Anion- and cation- ion-exchange resins KU-2 and AV-18 3rd INCC, September 18-23, 2011, Palermo, Sicily, Italy

  3. The absorption of I2 and CH3I on anion-exchange resin AV-18 from the water coolant of WWER-type NPPs* * The water coolant of the WWER-type NPPs: [NaCl] = 1.17 mg/dm3; [NH4Cl] = 29.96 mg/dm3; [H3BO3] = 5 g/dm3;pH 7 - 8.5 3rd INCC, September 18-23, 2011, Palermo, Sicily, Italy

  4. Distribution coefficients Kd forI2 and CH3I on anion-exchange resin AV-18 from the water coolant of WWER-type NPPs (V/m =100; [CH3131I] = 10-5 M; [I2] = 910-4 M) * The water coolant of the WWER-type NPPs: [NaCl] = 1.17 mg/dm3; [NH4Cl] = 29.96 mg/dm3; [H3BO3] = 5 g/dm3;pH 7 - 8.5 3rd INCC, September 18-23, 2011, Palermo, Sicily, Italy

  5. Aim of the work is to develop a new effective material to absorb molecular and organic iodine from water solutions It is desirable to employ materials that are used on working NPPs to coolant decontamination Ion-exchange resin - KU-2 3rd INCC, September 18-23, 2011, Palermo, Sicily, Italy

  6. Some characteristics of the new materials based on cation-exchange resin KU-2 IPCE-C1 - about 8.0 wt.% of Cu IPCE-C2 - about 5.5 wt.% of Cu IPCE-CS - the total content of metals about 10.0 wt.% at molar relation Cu : Ag = 4 : 1

  7. Distribution coefficients Kd for131I-, 131IO3-, CH3131I and I2on the modified resin KU-2 from a water coolant of the WWER-type NPPs* (V/m =100; [K131IO3] = 10-5 M; [K131I] = 10-5 M; [CH3131I] = 10-5 M; [I2] = 910-4 M Time of contact between liquid phase and material is 120 min) * The water coolant of the WWER-type NPPs: [NaCl] = 1.17 mg/dm3; [NH4Cl] = 29.96 mg/dm3; [H3BO3] = 5 g/dm3;pH 7 - 8.5 3rd INCC, September 18-23, 2011, Palermo, Sicily, Italy

  8. Dependence of I2 sorption on the time of contact between solid and liquid phases

  9. THANK YOU ! 3rd INCC, September 18-23, 2011, Palermo, Sicily, Italy
