  目的 了解不同吸收剂(四氯汞钾吸收液、甲醛吸收液)对空气中二氧化硫测定结果的影响 ,为改进二氧化硫测定方法提供参考。方法均采用国家标准方法进行空气中二氧化硫的测定,比较测定结果 是否有差异, 对比两种方法的精密度 及准确度 。结果对测定结果的两组数据进行 t检验,所测得的空气中二氧化硫浓度差异无统计学意义 。四氯汞钾吸收法的准确度以及精密度优于甲醛吸收法。古代女子把手称白荑男子的手称为什么?,结论 确定四氯汞钾吸收法为今后工作中二氧化硫测定的主要方法。

  Objective To understand the different absorbent (potassium absorption fluid mercury tetrachloride, absorbing solution) to the results of sulfur dioxide measured the impact of sulfur dioxide to improve the determination of reference. National standards were adopted in the method of determination of sulfur dioxide, more determined whether the results are different compared two methods of precision and accuracy. Results on the test results carried out two sets of data t test, the measured concentration of sulfur dioxide in air was no significant difference. Potassium mercuric tetrachloride absorption accuracy and precision is better than formaldehyde absorption. Conclusion determine tetrachloromercurate potassium absorption of sulfur dioxide for the determination of future work in the main method.

  To learn more about the different absorber (PCE pyrazophos absorbent, formaldehyde absorption liquid sulfur dioxide in the air) effects, to improve the determination of sulphur dioxide. Methods are provided in a national standard methods for the determination of sulphur dioxide in the air, comparing test results if there is a difference between two methods of precision and accuracy. Results on the results of two sets of data for t-test, measured the difference in the concentrations of sulfur dioxide in the air without statistically. Four of mercury absorption method is superior to the accuracy and precision of formaldehyde absorption method. Conclusion determines four chloride pyrazophos absorption method for the determination of sulfur dioxide in future work.
