The international standards to determine A in water quality and soil quality are both B methods. The Chinese standard to determine A in water quality now is still adopt C method which was abolished by ISO. However, the C method provides unstable testing results and has certain toxicity by using large amounts of D. What’s more, it also has some disadvantages of more reagents, complex operation, and determination of one element at one time. And that in soil is E method. Compared to B method which is adopted by ISO, the main advantage of the E method is the improved limit of detection, typically 10 to 20 times. However, the B method has the most serious disadvantage of poor resistance against atomization interferences and often unsatisfactory linearity of calibration curves. The US EPA has proposed a method of F for the analysis of A in water. It requires few reagents and instruments, but more interference is obtained. 句子的意思是： 目前国际上均采用B方法测定水质和土壤中A，中国的国家标准中仍采用ISO已经废止的C方法测定水质中A。然而，C方法测定结果不太稳定，并且大量使用具有一定毒性的D。此外，C方法还需要较多试剂，操作繁琐，一次只能测定一个元素。中国国家标准方法中测定土壤中A采用的是E方法。与B方法相比，E方法最显著的优势在于提高了10-20倍检出限。然而，B方法的最大缺陷在于抗原子化干扰较差，经常导致校准曲线线性不令人满意。美国EPA建议采用F方法测定水中A，该方法虽然只需较少仪器和试剂，但是却带来较多干扰。 |

楼主铁公鸡。。 B method is the international standards to measure A in both water and soil. The Chinese standard still adopts expired ISO method C to analyze A in water. However, the C method provides inconsistent test results and requires/consumes a large amount of D with high toxicity. Furthermore, it also has some disadvantages including demand of many reagents, complexity and low efficiency (1 element per test). E method is adapted in the chinese standard as of now. Compared to ISO B method, the E method shows an improved detection limit, typically by a factor of 10 to 20. Moreover, the B method has poor resistance against atomization interference and often displays NONLINEAR calibration curves. The US EPA SUGGESTS TO USE METHODE F for the analysis of A in water. It requires LESS reagents and instruments, but more interference CAN BE OBSERVED. 哥们，你英语要练阿。。。  |
