摘　　要：选取荧光化合物1,5-萘二磺酸,拟将其用于海水循环冷却系统浓缩倍数的跟踪监测,分析了其在纯水中的光谱特性,考察了海水盐度对荧光光谱的影响;另外,采用静态海水阻垢性能试验模拟海水循环冷却系统中温度、盐含量和p H值的变化,综合评价了对1,5-萘二磺酸荧光特性的影响。结果表明,1,5-萘二磺酸的荧光信号稳定,能够有效跟踪监测海水循环冷却系统浓缩倍数的变化。Fluorescent compound, 1,5-naphthalenedisulfonic acid was selected to track and moni- tor the cycle of concentration （COC） of seawater circulating cooling system. The spectrum characteristics of 1,5-naphthalenedisulfonic acid in pure water were analyzed. The effect of seawater salinity on the fluo- rescence spectrum of 1,5-naphthalenedisulfonic acid was investigated. Under the conditions of static scale inhibition performance test, the changes of temperature, salt content and pH value in seawater circulating cooling system were simulated, and the influences of these parameters on fluorescence characteristics of 1,5-naphthalenedisulfonic acid were comprehensively evaluated. The results showed that the fluorescence signal of 1 ,5-naphthalenedisulfonic acid was stabile and could effectively track and monitor the change of COC.
