摘　　要：目的 探讨测定废水中Cr6+的新方法。方法 采用电感耦合等离子体发射光谱法,样品经离子交换法分离,浓缩。结果 精密度为2.05％,平均回收率为99.7％,最低检出限为0.018μg/ml。结论 用本方法测定工业废水中Cr6+,可能对排除水样中干扰物质的影响。ve To study the new method for determination of chromium (Ⅵ) in waste water. Methods The chromium (Ⅵ) from waste water samples was seperated by ion-exchange method and concentrated, then was analyzed by inductively coupled plasma-atomic emission spectrometry. Results The precision, average recovery rate and detection limit were 2.05%, 99.7% and 0.018μg/ml respectively. Conclusion This method was easy and rapid to operate, and revealed less interference in determination of chromium (Ⅵ) in industrial waste water.
