摘　　要：提出用Ｍｏ６＋－ＮＨ２ＯＨ－ＤＴＰＡ螯合物，滴定法测定钼的含量。ＣＸ－ＰＡＲ－ＭＧ为混合指示剂、Ｃｕ２＋标准溶液进行返滴定，终点颜色变化格外敏锐。一般常见金属离子都不干扰，该法已用于测定钼精矿、钼铁中的钼，结果十分满意。The chelatometric determination of molybdenum using molybdenum(Ⅵ)-hydroxylamine-DTPA chelates.CX-PAR-MG as mixed indicator and backtitrated with Cu2+ standard solution,the change of endpoint is more sensitive.Normally encoumtered metal ions were not found to interference.The method has been for the determination of molybdenum in molybdenum concentrate and ferromolybdenum with satisfactory results.
