Question

哪位高手帮我翻译一下英文吧~我水平有限!!谢谢啊!!感激......

One hundred milliliter of sample was introduced into a 2 50-ml beaker at room temperature(25C).The pH of the sample was adjusted by adding sulfuric acid.20 g/L of FeSO4•7 H20 and 3% H202 were then added to the sample and the mixture was stirred and left at a standstill for 1h .After sedimentation,the supenratant was withdrawn for COD and color analysis.
Experiments (not presented here)conducted on the pharmaceutical wastewater for the selection and optimization of coagulants (A12(SO4)3 polyaluminum chloride (PAC), FeCl3 and polyferrie sulfate (PFS)) Showed that A12(SO4)3
Performed well by f ar.Thus, the coagulation process was performed using sulfate aluminum (A12(SO4)3) as coagulant, at the pre-determined optimal concentration and pH value of 800 mg/L and 5 ,re spectively.
After the Fenton's reaction, the coagulant (A12(SO4)3) was added to the sample with rapid mixing at 300 r/min for 0.5 min, followed by slow mixing at 50 r/min for 10 min. After 30 min of sedimentation, the supernatant was withdrawn for COD and color analysis.
One thousand milliliter of sample was introduced into a given beaker containing 100.0 μg of hexahydrothymol
as internal standard. 10% NaOH was employed to adjust the pH (PH≥1 1).Basic contents of the sample were then extracted 3 times by 50 ml of dichloromethane.The pH of the remaining liquor w as adjusted to a pH o f 2 u sing 6 mol/L H 2SO4, an d acidic contents were extracted as described above. The two extracted liquors were brought together and dried for about 24 h by anhydrous sulfate sodium, and finally evaporated to 1.0ml in K-D (Kudema-Danish evaporator). 1.0 μ1 of the remaining liquor was withdrawn for GC-MS analysis.
Finnigan Voyager was used as analytical tool for gas chromatography-mass spectrometry (GC-MS) analysis, with DB-5 silica capillary column (30 m x 0.25 mm, 0.25 μm). The column temperature was programmed from 50℃ (for 2 min) to 300℃ (for 10min) with a heating-up velocity of 10}C /min, carrier gas of He was 1.0 ml/min, and a split ratio of 20:1. Source temperature was held at 200`C, ionization energy at 70 eV (electron volt). Interpretation of the
resulting chromatograms and mass spectra was performed using NIST (National Institute of Standards and Technology) library.

Answer 1

100毫升样品被引入了250毫升的烧杯,在室温下(25c). pH的样品 调整了添加硫酸acid.20g/l硫酸亚铁•7h20和3%h202然后再加标本及 混合搅拌和左处于停顿8.91%. 经过沉淀,supenratant被撤回,COD和色度分析.

实验(这里没有介绍)进行的制药工业废水的优选混凝剂(a12(so4)3聚合氯化铝(PAC) FeCl3和polyferrie硫酸(加油站))显示a12(SO4)3的表现不错的Far.thus, 凝血过程是用硫酸铝(A12号(so4)3)作为混凝剂, 在预先确定的最佳浓度和pH值为800毫克/升和5,再spectively.

之后芬顿反应 混凝剂(a12(so4)3)增加了样品的快速混合,在300r/分钟,0.5分钟, 其次是缓慢的搅拌在50r/分钟,10分钟. 30分钟后,沉淀,上清撤回COD和颜色分析

1000毫升样品被引入某一烧杯中含100.0克hexahydrothymol

作为内部标准. 10%氢氧化钠用来调整pH值(pH值大于1). 基本内容的样本,然后抽取3倍 50毫升
dichloromethane.The 酸碱度残余的酒w 依照对酸碱度o f 2 u 被调整唱6 mol/L H 2SO4, 酸性内容被提取如上所述的d 。二提取的酒被带来了和被烘干了为大约24 h 被无水sulfate 钠, 和最后被蒸发了对1.0ml 在K-D (Kudema 丹麦蒸发器) 。残余的酒的1.0?1 被撤出了为GC-MS 分析。
