摘要
对EDTA容量法测定水中硫酸根时 ,对加入沉淀剂后样品静置时间对测定结果的影响进行了研究。结果表明 ,在本法规定的浓度范围内 ,样品静置时间对测定结果无影响。
This paper discusses the effects of sample resting when precipitating agent is added on experiment results by using EDTA volumetric method for the determination of SO 2- 4 in water.The resut shows that resting time doesn,taffect determination data in the concentration range of this method.
