The MBT decomposed in the water containing active chlorine,but BTA could sustained in the water containing Cl 2,ClO 2 with pH 8.5.The BTA could be affected by Br 2,BCDMH and sunlight.

• 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。
