摘要/Abstract

摘要： 乙醇胺（ETA）是我国第三代核电确定采用的二回路水质调节碱化剂，二回路中微量ETA浓度的测定及干扰问题是关注的焦点之一。系列试验表明，无干扰离子时，3种色谱分析柱（CS12A、CS16、CS18）都能准确测定ETA浓度。在模拟核电站二回路水质条件下，重点探讨了使用CS18分析柱测定ETA时NH₄⁺、Li⁺、Na⁺、K⁺、Mg²⁺、Ca²⁺、吗啉的干扰问题。结果表明：通过优化色谱条件，在柱温50 ℃、抑制电流20mA、淋洗液流速0.36mL/min、梯度淋洗方式下，可以准确测量核电站二回路水中微量ETA浓度。

Abstract: Ethanolamine (ETA) has been selected as the pH control agent for the secondary loop water quality regulation in the third-generation nuclear power plant of China. Hence the determination and interference analysis of trace ETA in the secondary circuit is becoming one of the critical issues that have captured attentions. On the basis of a series of experiments it is discovered that these chromatographic columns (CS12A, CS16, CS18) can determine the concentration of ETA accurately without any other ions. Under the condition of simulated second-loop water quality in the nuclear power plant, the interference of Li⁺, Na⁺, K⁺, Mg²⁺, Ca²⁺ and morpholine was mainly discussed when using CS18 analytical column to determine the concentration of ETA. The results showed that through the optimization of the chromatographic conditions, the concentration of trace ETA in the second-line water quality of nuclear power plants can be accurately measured with gradient elution when the column temperature is 50℃, the inhibition current is 20 mA and the eluent flow rate is 0.36 mL/min.

Key words: secondary loop in the nuclear power plant, ion chromatography, ethanolamine, interference experiment, CS18
