FENTON氧化方面的問題 已有2人參與
|
|
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,這句話是關(guān)于fenton氧化方面的一句英文,請問這句話怎么翻譯合適呢,不勝感激! |

pH值小于3,攪拌速度達(dá)到700轉(zhuǎn)/分鐘的實驗條件,可以保證Na2SO3與濃度高于0.469MM的鐵離子反應(yīng)時有足夠好的氧化效果。(有點(diǎn)不像人話。。。后面半句太長了。。。 要保證Na2SO3與濃度高于0.469MM的鐵離子反應(yīng)時有足夠好的氧化效果,需要的實驗條件是pH值小于3,攪拌速度達(dá)到700轉(zhuǎn)/分鐘。(稍微好了點(diǎn)點(diǎn)。。。然而重點(diǎn)放在了后面,沒有強(qiáng)調(diào)的感覺了。。。 pH<3,攪拌速度達(dá)到700rev/min,可以保證Na2SO3與高濃度的鐵離子(>0.469MM)反應(yīng)時有足夠好的氧化效果。(簡單粗暴款。。。 想不出來了,樓主好運(yùn)~~ |

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. |
