摘　　要：研究了空气－乙炔火焰原子吸收光谱法间接测定微量锆的方法，在弱酸性溶液中钢与Ｎ－亚硝基苯胲（铜铁试剂）形成１：２络合物可被氯仿定量萃取，Ｚ ｒ（Ⅳ）定量置换Ｎ－亚硝基苯胲钢中的铜，原子吸收光谱法测铜间接测锆，特征浓度为 ０．０７ × １０－６ ｇ／ｍＬ／１％，线性范围为 ０～５ｍｇ／Ｌ，方法简便、快速、灵敏度高，选择性好，用于瓷釉和α－βＡｌ２Ｏ３中氧化锆的测定，结果满意。The zirconium was determined indirectly based on the replacement of Cu in copper-N- Nitrosophenyl hydroxylamine by Zr(Ⅳ), and then determinaed Cu in the replaced solution by atomic absorption spectrometry. The sensitivity for the determination of zirconium is 0.07 × 10-6 mg/L/1%, the linear calibration curve is obtained in the ragne of 0-5. 0 mg/L, The methods is selective and highly sensitive. It has ho applied to the determination of trace zirconium in α-βAl2O3 and porcelain glaze samples with satisfactory results.
