电感耦合等离子体原子发射光谱(ICP-AES)法测定工业废水中的颜料绿58

Determination of C.I.Pigment Green 58 in Industrial Wastewater by Inductively Coupled Plasma Atomic Emission Spectrometry(ICP-AES)

建立了硝酸溶解-电感耦合等离子体原子发射光谱(ICP-AES)法测定工业废水中颜料绿58的分析方法。方法前处理简单,在选定的条件下,检出限为3.0×10-3 mg/L,方法的相对标准偏差小于3%,样品加标回收率在95.0%~105%。方法准确,快速,可用于水中颜料绿58的定量分析。

In this article,inductively coupled plasma-atomic emission spectrometry （ICP-AES） was applied to analyze C.I. Pigment Green 58 in industrial wastewater with simple pretreatment method. Under the optimal conditions, the limit of detection（LoD） was 3.0×10^-3 mg/L, the relative standard deviation （RSD） was less than 3% and recoveries from 95.0% to 105% was recorded. The method can be applied for accurate and rapid quantitative analysis of C. I. Pigment Green 58 in industrial wastewater.
