AN250: Determination of Trace Nickel and Zinc in Borated Power Plant Waters Containing Lithium Hydroxide Using Nonsuppressed Conductivity Detection
Description
Boron as boric acid is used to control the nuclear reaction in pressurized water reactors (PWR) because of its strong neutron-absorbing characteristics. In addition, lithium is added to adjust the pH and zinc is added to suppress cobalt (58Co, 60Co) activity. Dissolved Ni in these solutions can be indicator of stress corrosion. To minimize corrosion, Ni and Zn monitoring is needed. Here µg/L of Ni and Zn in borated lithium water samples are determined on IonPac SCS-1 column and detected by non-suppressed conductivity. We recommend AN277 if sub-ppb detection is needed.| Market: | Water Analysis |
