Determination of boron, beryllium and antimony in wastewater by Inductively coupled plasma optic emission spectrometry

本文建立了硝酸消解环境监测领域中成分复杂的污水水样,电感耦合-等离子体发射光谱仪（ICPAES）同时测定水中3种重金属硼、铍和锑的方法。结果表明,硼、铍和锑的检出限分别是0.044、0.004和0.040mg·L-1,加标回收率为96.3%~101%,相对标准偏差均≤2%。方法简单、快速,适合环境水样检测,结果满意。该方法快速、简便,检出限低。

In this paper, a new method for the determination of Boron（B）, Beryllium（Be） and Antimony （Sb） was developed by Inductively Coupled Plasma Optic Emission Spectrometry（ICP-OES）. The samples were digest- ed with nitric acid medium. The results showed that the detect limits of B, Be and Sb were 0.044, 0.004 and 0.040 mg. L-l, respectively. The recoveries of B, Be and Sb were 96.3%-101%, and the relative standard deviations （RS- Ds） were less than 2%. The proposed method has simple operation and rapid analytical speed, and it is suitable for the determination of B, Be and Sb in environmental samples with satisfactory results.
