氯化亚锡在分析中的研究

Inorganic Phosphorus in Water Cycle of the Total Determination of Improvement

还原剂硫酸肼对呼吸道有强烈刺激性,吸入引起咳嗽、头晕、恶心和呕吐。高浓度吸入引起震颤和惊厥。对眼和皮肤有刺激性,可致灼伤。长期接触引起肝、肾和皮肤损害。吸光度不太稳定、测定范围较窄。用还原剂氯化亚锡取而代之可避免这个缺点,并且作出的准确度高,偏差小。

The reducer sulfuric acid hydrazine has intense pungency to pneogaster,sucks in arouse tussis,dizzy,nauseous and vomiting.High concentration is sucked in arousing the tremor and the eclampsia.The cross-eye and skin have pungency,but cause a burn.The long range is contacted arousing liver,kidney and skin damage.Suck luminosity is not very stable,admeasurement range is narrower.And chlorinating Yaxi replaces it but avoid this shortcoming with the reducer,accurate degree making is high,deviation is small.
