摘要
研究了利用离子色谱测定地表水和电镀废水中的Cr(Ⅵ)。研究结果表明,离子色谱法测定Cr(Ⅵ),测定标准样品的相对误差低于2.5%,多次测定的相对标准偏差低于2.2%。在含有较高浓度的其他无机阴离子时,检测结果不受干扰,而且检出限为0.012mg/L。
The determination of chromium(Ⅵ) in water and waste water by ion-chromatography and direct electric conductivity detector was developed. No interference was observed when other ions with high concentration existed. The detection limit was 0.012 mg/L.
