生乳中次氯酸钠的检测研究OA
Study on sodium hypochlorite in raw milk
建立了生乳中次氯酸钠的检测方法。试样中次氯酸根在弱酸性条件下与碘化钾生成游离碘,以淀粉溶液为指示剂,硫代硫酸钠标准滴定溶液滴定,计算氯的含量。方法处理简单,易操作,回收率高,试验成本低,分析周期短,因此该方法可作为生乳中次氯酸钠的快速检测方法。
A method is developed to detect sodium thiosulfate in raw milk. In the weak acidic medium, hypochlorite in sample reacted with potassium iodide to form free iodine which was then titrated with the standard solution of sodium thiosulfate, using starch solution as indicator, to calculate the content of chlorine.The approach is simple and easy to operate, high recovery ratio and low cost, analysis period is short, so it can be used as a rapid detection method o…查看全部>>
