| 摘 要： | 用电镀锌板对废水中的有机污染物进行了降解。在碘钨灯照射下,电镀锌板对偶氮染料和氯代有机物的还原降解速率倍增。对不同有机污染物的降解活性测试及XPS测试的结果显示:光照下电镀锌板对偶氮染料和氯代有机物的还原降解遵循典型的零价金属还原降解有机物的机理。入射光通过激发有机物分子或可能的有机物——Zn0复合物,加速了有机物分子和Zn0之间的电子转移还原过程。电镀锌板还原降解活性具有较好的持久性,在多次使用后未发现明显变化。

| Abstract: | Electrogalvanizing zinc plate was used to degrade the organic pollutants in wastewater.(Reducing) degradation rates of azo dyes and chloroorganics by the electrogalvanizing zinc plate were greatly increased under the irradiation of an iodine-tungsten lamp.Measurement results of degradation activities of various organic pollutants by electrogalvanizing zinc plate and XPS show that the reducing degradation of azo dyes and chloro-organics under irradiation also follows general laws of zero-valent metal reducti... |
