1)  sulfur separation
析硫
1.
By buffering the pH value of the solution, preventing carbon dioxide from penetrating into the solution, and strengthening the management of the analysts, sulfur separation from sodium thio-sulfate standard soluti.
 溶液的酸度、二氧化碳、空气、微生物、光照及人为和环境等因素对硫代硫酸钠标准溶液浓度的稳定性有很大的影响,继而造成氮肥生产中有关碘量分析法的误差,通过控制溶液的pH值,防止二氧化碳气体的渗入,加强对分析人员的管理,可从根本上解决生产实际中硫代硫酸钠标准溶液出现的析硫现象,保持其浓度的稳定性。
