1) subacid solution
微酸性溶液
1.
In subacid solution of PH values 3~4,ammonium-bifluoride is used to mask Fe 3+,where bivalent copper reacts with potassium iodide to form copper iodide precipitation and precipitate iodine,and with starch as an indicator,the standard solution of sodium thiosulfate is used to titrate the precipitated iodine,by which the content of copper can be determined.
本方法基于PH值3～4的微酸性溶液中,用氟化氢铵掩蔽Fe3+,二价铜与碘化钾反应生成碘化亚铜沉淀并析出碘,以淀粉为指示剂,用硫代硫酸钠标准溶液滴定所析出的碘,既可测定出铜的含量,并对分析方法的理论进行了探讨。
