摘要:
建立了全自动石墨消解-电感耦合等离子体发射光谱法测定染整企业废水中总锑的测定方法。结果表明,锑的质量浓度在0~10 mg/L范围内线性关系良好,R值为0.999 5,方法检出限和测定下限分别为0.003和0.012 mg/L,相对标准偏差(RSD)为0.17%~2.6%,加标回收率为96.1%~103.8%。该方法操作简单、分析快速,符合技术规范要求。

Abstract:
Graphite digestion furnace ICP OES was applied to the determination of total Sb in dyeing wastewater. The results showed good linear relationship between emission intensity signal and concentration of Sb in the range of 0~10 mg/L with R value 0.999 5. The method detection limit (MDL) and limit of quantitative determination (LQD) were 0.003 and 0.012 mg/L, respectively. The relative standard deviations (RSD) ranged from 0.17%~2.6%. The recoveries were recorded at a range of 96.1%~103.8%. This method was simple and rapid, and meets the requirement of technical specification.
