Introduction of GB/T 4701.6-2008

本部分代替ＧＢ／Ｔ４７０１．６—１９８４《钛铁化学分析方法　８-羟基喹啉容量法测定铝量》。本部分规定了EDTA滴定法测定钛铁中铝的含量。本部分适用于钛铁中铝含量的测定，测定范围：3.00%--12.00%。本部分与ＧＢ／Ｔ４７０１．６—１９８４相比较，主要进行了以下技术修改：
———试料量由０．５０ｇ调整为０．２５ｇ；
———采用硝酸、氢氟酸、硫酸分解试料，残渣进行回收处理代替盐酸、硝酸分解试料；
———采用盐酸—六次甲基四胺分离干扰元素，代替８羟基喹啉分离干扰元素的过程；
———采用ＥＤＴＡ滴定法代替加入过量的溴酸钾标准滴定溶液，再加入碘化钾生成碘，以淀粉为指示剂，用硫代硫酸钠标准滴定溶液滴定的方法。
