摘要
实验室依据GB/T 11060.2-2008建立实验方法,在标准色阶配制过程中发现,国标规定的用硫化钠制备标准比色溶液的方法不完善,是测量结果不确定度的主要来源。通过改进实验方案,优化实验条件,建立了亚甲蓝法测定天然气中硫化氢的实验方法,提高了测定结果的准确性和安全性。
The laboratory establishes the experiment method according to GB/T 11060.2-2008.In the process of standard color order configuration,the method in the preparation of standard colorimetric solution with sodium sulphide is imperfect,which is the main source of uncertainty of measurement results.By improving the experiment plan and optimizing the experimental conditions,the experimental method on determination of hydrogen sulfide content by methylene blue method is established,which improves the accuracy and safety of the determination results.
