This is a necessary step because some of the starch degradation products in the presence of the sodium hydroxide used in scouring form strong reducing agents that can cause color changes in dyed materials.

此阶段很重要,这是因为降解淀粉的产物遇到在煮炼中使用的氢氧化钠时,会形成还原剂,还原剂会使染色的织物褪色。

From the above discussion, the degradation pathways for aniline by O3 were obtained as illustrated in Fig.6.

从以上讨论,可以得出如下苯胺臭氧氧化降解的降解途径,如图6所示。

However, when the pH rises to a certain value, the degradation rate of aniline will drop.

但当pH值升到一定程度以后,去除率又有所下降。

However, with further increasing of ozone flowrate, the mass transferring efficiency decreased, resulting in a higher removal rate and lower degradation velocity of TOC.

但随着O3流量的增大,传质效率会进一步降低,故TOC去除率提高速度变缓。
