| 摘 要： | 分析试样中加入过量ＦｅＣｌ３溶液，经搅拌使试样中金属铝与Ｆｅ＾３＋离子发生化－还原反应，生成Ａｌ＾３＋进入溶液中，三氧化二铝不参与反应仍留在沉淀物中。过滤后含Ａｌ＾３＋溶液经除氟，分离钙、镁、铁等离子后，用ＣｕＳＯ４滴定法测定ＭＡｌ量，再由总铝量减去ＭＡｌ，计算可得ＡＤ复合脱硫剂中Ａｌ２Ｏ３含量。

| Abstract: | The excessive FeCl 3 solution is added into the analytical sample.The metallic aluminiun (MAl) in the sample is made to oxidizing-reducing react with Fe 3+ by means of stirring,resulting Al 3+ coming into solution.The Al 2O 3 doesn't react,retains in the precipitate.After fluorine is removed and calcium,magnesium and iron separated from the Al 3+ bearing filter liquor,the MAl content is determined with CuSO 4 titrimetry,the MAl content is subtracted from the total Al content,then the Al 2O 3 content is calculated. |
