摘　　要：研究了SC260海水阻垢剂在水体系中的荧光光谱特性,探讨其与惰性示踪剂1,5-萘二磺酸共用时的荧光光谱相互作用,测试了其在静态海水阻垢性能评价试验条件下的消耗量,评价了其阻垢效果。结果表明,SC260海水阻垢剂在激发波长300 nm以上有着特殊独立吸收和发射光谱区,最大峰强出现在激发波长为380 nm、发射波长为521 nm处;它与1,5-萘二磺酸可在同一体系中进行分析鉴定;SC260海水阻垢剂在浓海水中的阈值效应明显,有良好的阻垢性能,适用于海水循环冷却系统。The fluorescence spectrum characteristics of seawater antiscalant SC260 were studied, and its interactions with 1,5-naphthalenedisulfonic acid were described. An evaluation test of static scale inhibition performance was constructed to determine the consumption and evaluate the performance. The experimental results indicated that seawater antiscalant SC260 had special independent absorption and e- mission spectrum over 300 nm, where the maximum peak of excitation wavelength was 380 nm and the maximum peak of emission wavelength was 521 nm. SC260 could be analyzed in the same system inclu- ding 1,5-naphthalenedisulfonic acid. SC260 had obvious threshold effect in the concentrated seawater and showed good performance. It was suitable for the application in seawater circulating cooling system.
