３．５催化动力光度法测定轻水堆水中痕量铜杨姣兰，王凌本方法将物理化学的催化动力法与分光光度法结合起来，首次将催化动力光度法用于反应堆主回路水中痕量铜的监测。方法灵敏度高达８×１０￣（－１１）ｇ（Ｃｕ￣（２＋））／ｍｌ，回收率大于８９％，相对标准偏差小... 3.5 Catalytic kinetic spectrophotometry for the determination of trace copper in light water reactor Jiao-Lan Wang, Ling Wang This method combines the physico-chemical catalytic kinetic and spectrophotometric methods for the first time using catalytic kinetic spectrophotometry for the monitoring of trace copper in the reactor main circuit water . The sensitivity of the method is up to 8 × 10 ~ (-11) g (Cu ~ (2 +)) / ml, the recovery rate is over 89% and the relative standard deviation is small.
