This was possibly due to the instability of TETA. Trough long-term leaching, TETA fell out for erosion.
这可能因为TETA形成的钝化膜并不稳定，经过长期的侵蚀作用而逐渐脱落。
Results showed that TETA had certain effect on the leaching process. However, as the time went, its effect became weak.
结果表明，TETA对尾矿具有一定的钝化效果，但随着时间的延长，钝化效果逐渐减弱。
From the study on the physicochemical properties, it was shown that TETA-DGEPG-EPON834 had good water-solubility ability and favorable surface performance.
通过其理化性能的研究，结果表明TETA -DGEPG -EPON834具有优良的水溶性和良好的表面活性。
In addition, through using TETA to passivate the tailing surface, the capability of its anti-chemical oxidation and anti-biological oxidation both before and after passivating was studied.
此外，运用TETA对尾矿进行表面钝化处理，研究钝化前后尾矿抗化学氧化和生物氧化的能力。
