研究了在某电厂循环水的模拟水中 ,铜缓蚀剂BTA、MBT的抗氯稳定性 ,并介绍了BTA在其他氧化性杀生剂中的稳定性。研究结果表明 :MBT与活性氯不能共存 ;BTA抗活性氯氧化的性能较好 ,在模拟现场条件下 ,基本上不分解 ,但温度和光照对其抗氯性影响较大 ,尤其是光照 ;pH值为 8.5时 ,投加Cl2 、ClO2 的冷却水系统中 ,BTA基本上不会受到影响 ,但溴类氧化剂BCDMH、Br2 与BAT之间反应十分迅速 ,几乎在 1h内反应完全。
The chlorine stability of copper corrosion inhibitors BTA and MBT in simulated water of circulating water in a power plant was studied. The stability of BTA in other oxidizing biocides was also introduced. The results showed that MBT could not coexist with active chlorine. The activity of BTA was better than that of active chlorine. Under the simulated field conditions, BTA did not decompose basically, but temperature and light had a great influence on the chlorine resistance, especially the light The value of 8.5, the addition of Cl2, ClO2 cooling water system, BTA basically will not be affected, but the brominated oxidants BCDMH, Br2 and BAT reaction was very rapid, almost 1h reaction.
