摘 要：
采用微波活化过硫酸盐处理活性艳红K-2BP染料废水,分别考察了活性艳红K-2BP初始浓度、过硫酸钠用量、微波功率以及pH等因素对活性艳红K-2BP脱色效果的影响。结果表明:对于初始质量浓度为500mg/L活性艳红K-2BP废水,当活性艳红K-2BP/PS摩尔比为1∶5、微波功率为460W时,反应8 min后,活性艳红K-2BP的脱色率达到97%。pH几乎不影响活性艳红K-2BP脱色率。通过对比试验发现微波活化过硫酸盐能高效地降解活性艳红K-2BP废水。进行UV-Vis光谱分析,发现除了可见光区域的发色基团得到降解外,在紫外区的苯环和萘环也被破坏。COD的去除率最高可达到85%。

摘 要：
Brilliant Red K-2BP wastewater was treated with microwave-activated persulfate oxidation.The influences of initial wastewater concentration,persulfate amount,microwave power and pH on degradation effect were investigated.The results indicate that the degradation rate of 500 mg/L Brilliant Red K-2BP wastewater gets to 97% within 8 min when Brilliant Red K-2BP/PS molar ratio is 1∶5,microwave power is 460 W.The values of pH hardly influence the decolorization rate of Brilliant Red K-2BP.It is found from the contrast experiments that microwave-activated persulfate oxidation is able to degrade Brilliant Red K-2BP wastewater efficiently.The UV-Vis spectrogram analysis shows that with the degradation of visible light chromophore band of Brilliant Red K-2BP and benzene ring,naphthalene ring in the ultraviolet region are also destroyed.The best removal of COD is about 85%.
