中文名称:硫化铜浓缩物 铜含量的测定 滴定法.
英文名称:Copper sulfide concentrates — Determination of copper content — Titrimetric methods
发布日期:1994-06
标准范围
规定了测定15%(m/m)至50%(m/m)范围内硫化铜精矿中铜含量的两种滴定法,在分离(方法1)或未分离(方法2)铜与干扰元素后,通过碘离子与铜(II)离子与硫代硫酸钠反应分离出游离碘。
Specifies two titrimetric methods for the determination of the copper content of copper sulfide concentrates in the range 15 % (m/m) to 50 % (m/m), titrating free iodine isolated by reaction between iodide ions and copper(II) ions with sodium thiosulfate using soluble starch as the indicator after separation (method 1) or without separation (method 2) of copper from interfering elements.
