【摘要】 研究了在ＨＮＯ３介质中ＥＤＴＡ快速测定氟锆酸铵中ＺｒＯ２的方法。对于高纯样品采用返滴定法测定，对于含有杂质的样品采用直接滴定法。上述方法所测结果与重量法结果相近，方法简单、快速。更多还原

【Abstract】 The rapid determination methods of zirconium oxide in ammonium fluozirconate were studied in HNO 3 medium using EDTA complexometric titration. Back titration method was used to high purity sample and direct titration method was used to impurity sample. The results were basically same as the gravimetric method. The methods are simple, rapid and accurate.更多还原
