Determination of Chromium (Ⅵ) in Waste Water by Inductively Coupled Plasma-Atomic Emission Spectrometry / 环境与健康杂志

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 0.018?g/ml respectively. Conclusion This method was easy and rapid to operate, and revealed less interference in determination of chromium (Ⅵ) in industrial waste water.
