[求助] FENTON氧化方面的问题 已有2人参与

Solution pH below 3.0 and stirring speed of 700 rev min1 could ensure a sufficiently high oxidation rate for Na2SO3 with ferric ion higher than 0.469 mM
  各位大神,这句话是关于fenton氧化方面的一句英文,请问这句话怎么翻译合适呢,不胜感激!

全文发出来看看,就这一句话太难猜

Hydrogen peroxide interference on chemical oxygen demand (COD) measurement has been a big problem in the application of the Fenton process. However, there is no simple and effective method
available to address this problem, although several methods have been reported in the literature. In this study, a new method has been developed based on Na2SO3 reduction and O2 oxidation, which has easy operation and short time requirement. Na2SO3 reduction was used to remove H2O2 in water samples, which was independent of pH in the investigated range of 2.50–11.95. Residual Na2SO3 was removed by subsequent O2 oxidation, and effects of initial solution pH, ferric ion dosage, and stirring speed were explored. Solution pH below 3.0 and stirring speed of 700 rev min1 could ensure a sufficiently high oxidation rate for Na2SO3 with ferric ion higher than 0.469 mM. This new method was proven to be effective in the matrix of Fenton treating real landfill leachate. Meanwhile, the procedure for this method in other applications was proposed in detail. To the best of our knowledge, this newly
developed method is the most simple and effective way to avoid H2O2 interference on COD analysis.

pH值小于3,搅拌速度达到700转/分钟的实验条件,可以保证Na2SO3与浓度高于0.469MM的铁离子反应时有足够好的氧化效果。(有点不像人话。。。后面半句太长了。。。

要保证Na2SO3与浓度高于0.469MM的铁离子反应时有足够好的氧化效果,需要的实验条件是pH值小于3,搅拌速度达到700转/分钟。(稍微好了点点。。。然而重点放在了后面,没有强调的感觉了。。。

pH<3,搅拌速度达到700rev/min,可以保证Na2SO3与高浓度的铁离子(>0.469MM)反应时有足够好的氧化效果。(简单粗暴款。。。

想不出来了,楼主好运~~

亚硫酸钠主要起还原作用的嘛,所以我就迷惑在为什么是氧化效果呢,你觉得呢

这里亚硫酸钠的作用大概是还原催化剂铁离子,亚铁离子的催化效果比铁离子好。
亚硫酸钠在我的试验里是终止剂,这里确实有点不同。
要了解作者意图,要联系上下文啊~~
