摘　　要： 研究了在HCl介质中快速测定硫酸锆中氧化锆含量的EDTA络合滴定法及其滴定条件,采用重量法与容量法相结合,先以重量法测出硫酸锆中氧化锆含量,再以已知含量的硫酸锆标定EDTA标准溶液的滴定度,然后再测定相同原料生产的硫酸锆。该方法较重量法简便,快速,准确度较为满意。 The rapid determination of zirconium oxide in zirconium sulfate in HCl medium with EDTA compleximetric and its titration conditions were studtied. A method was introduced which combined the gravimetric analysis and volumetric analysis together to determine the zirconium oxide content of zirconium sulfate by gravimetric analysis at first, and used zirconium sulfate （whose zirconium oxide content was known） as the calibration agent to calibrate titer value of standard EDTA solution, then used the EDTA to determine the zirconium oxide content of zirconium sulfate produced with the same raw material. This analysis was simple, rapid than gravimetric analysis and its accurate was satisfactory.
