| 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. |
