The application of the wastewater containing heavy metal, dye, polychlorinated hydrocarbons and hardly biodegradable organics with zero- valent iron was summarized, and the characteristic as well as the prospect of the technology was discussed.
介绍了零价铁的性质及其处理污水的机理 ,概述了零价铁在处理含重金属、染料、多氯化合物、生物难降解有机物等废水的应用状况 ,评述了零价铁处理废水的特点及应用前景。
The results showed that the chlorine-induced degradation on PU soft segment occured and C-Cl compound formed under the attack of activated chloric atom.
结果表明，ＰＵ浸氯水后，因受活性氯原子的攻击，ＰＵ大分子软链段的碳－碳键发生断裂，形成碳－氯化合物，添加剂加入后，因与ＰＵ大分子的软链段形成螯合物，从而避免了活性氯原子的攻击，有效地保护了软链段，使氨纶耐氯性能明显改善。
