有两位大侠翻译的还不错,但为什么显示不出来呢,我也无语了!

呵呵,英语大侠如果没有专业背景通常是翻译不好专业文章的。

采用硫酸溶解锑锭样品,盐酸溶解三氧化二锑样品, 用氢氧化钠溶液使Sb3+沉淀从而使基体锑与微量砷分离,

With sulfuric acid to dissolve block antimony samples, or with hydrochloric acid to dissovle antimony sesquioxide samples, the resulting solution was then treated with sodium hydroxide solution to precipitate Sb3+ so that trace arsenic could be seperated from antimony substrate.

通过加入硫脲-抗坏血酸将As5+还原成As3+,然后在原子荧光仪上测定锑锭及三氧化二锑中的砷。

After As5 + reduced to As3+ by thiourea and ascorbic acid, the contents of arsenic in block antimony or antimony sesquioxide samples was determined with atomic fluorescence spectrometer.

对氢化物发生条件进行考察,确定还原剂硼氢化钾的浓度为25 g/L、测定介质为20 % HCl(V/V)、硫脲-抗坏血酸溶液用量为5 mL。

The conditions of hydride generation was examined, and the concentration of reductant potassium borohydride was established to 25 g/L, determination medium to 20% HCl (V/V) and the amount of thiourea-ascorbic acid solution to 5 mL.

共存元素干扰试验表明,沉淀后溶液中残留少量锑的干扰在加入1 mL酒石酸溶液后可以完全消除,而样品中其他杂质元素在加入硫脲-抗坏血酸溶液后不干扰砷的测定。

The interference tests with coexisting elements indicate that interference from residual antimony in solution after precipitation can be eliminated completely by adding 1 mL tartaric acid solution, and interference from other impurities eliminated already after adding of thiourea-ascorbic acid solution.

方法的检出限为0.156 ng/mL 。对锑锭及三氧化二锑样品进行分析,相对标准偏差为0.95%~1.2%,测定值与国家标准方法的测定值相一致。

Detection limit of this method is 0.156 ng/mL. Relative standard deviation is 0.95% to 1.2% for block antimony and antimony sesquioxide samples, according with the determination by the
national standard.

最后一句没有按原文翻译,我猜测楼主的意思可能指相对标准偏差与国家标准一致。测定绝对值一致说服力不很强(不太可能完全没有差别,即便没有差别也要有统计数据说明)。

如有不明欢迎追问与讨论。

文章太专业了,要加分哟!!

采用硫酸溶解锑锭样品,盐酸溶解三氧化二锑样品, 用氢氧化钠溶液使Sb3+沉淀从而使基体锑与微量砷分离,通过加入硫脲-抗坏血酸将As5+还原成As3+,然后在原子荧光仪上测定锑锭及三氧化二锑中的砷。对氢化物发生条件进行考察,确定还原剂硼氢化钾的浓度为25 g/L、测定介质为20 % HCl(V/V)、硫脲-抗坏血酸溶液用量为5 mL。
The method adopted was to dissolve the antimony ingot sample with sulfuric acid, dissolve the antimony trioxide with hydrochloric acid, and isolate the antimony substrate from trace arsenium by using sodium hydrate solution to precipitate Sb3+, followed by reducing As5+ to As3+ with the addition of thiourea-arcosbic acid and then the arsenic content in the antimony ingot and antimony trioxide was determined through the use of an atomic fluorescence spectrometer. Observation was conducted on the condition of hydride generation and the concentration of reduction agent potassium borohydride was determined to be 25 g/L, determination medium 20 % HCl(V/V)and the dosage of thiourea-arcosbic acid solution was 5 mL.

共存元素干扰试验表明,沉淀后溶液中残留少量锑的干扰在加入1 mL酒石酸溶液后可以完全消除,而样品中其他杂质元素在加入硫脲-抗坏血酸溶液后不干扰砷的测定。方法的检出限为0.156 ng/mL 。对锑锭及三氧化二锑样品进行分析,相对标准偏差为0.95%~1.2%,测定值与国家标准方法的测定值相一致。
The coexist element interference test conducted had shown that the interference of small amount of residual antimony could be totally eliminated by adding 1mL of tartaric acid solution, and after the addition of thiourea-arcosbic acid solution, the rest of the impurity elements in the sample did not interfere with the determination of arsenic content. The detection limit of this method was 0.156 ng/mL. An analysis was conducted on the samples of antimony ingot and antimony trioxide, it was found that the relative standard deviation was 0.95% ~1.2%, the determined value was consistent to the determined value of the national standard method.

By using sulfuric acid dissolved antimony ingot samples dissolved in hydrochloric acid, three two oxidation antimony samples, using sodium hydroxide solution to make the precipitation of Sb3+ so that the matrix trace arsenic antimony and separation, by adding thiourea - ascorbic acid reducing As5+ into As3+, and then in the atomic fluorescence spectrometry determination of antimony ingots and three on two of arsenic in antimony oxide. On hydride generation conditions were investigated to determine the reducing agent, potassium borohydride concentration was 25 g/L, determination of medium for 20% HCl (V/V), thiourea L-ascorbic acid dosage was 5 mL. The interference of coexisting elements test indicates that, after a small amount of residual solution precipitation in antimony interference after adding 1 mL tartaric acid solution can be completely eliminated, while the samples in other impurity elements in adding thiourea - ascorbic acid solution does not interfere with the determination of arsenic. The detection limit was 0.156 ng/mL. On two and three oxidation antimony ingot antimony samples were analyzed, the relative standard deviation is 0.95%~ 1.2%, the measured values and the national standard method of determination of the same value.分享到
