摘要
采用DMA-80型直接测汞仪测定工业废水中的痕量汞,优化了干燥时间、分解温度、释放温度等试验条件。方法在0μg/L^600μg/L范围内线性良好,检出限为5.0×10-5mg/L,工业废水样品平行测定的RSD≤0.2%,加标回收率为96.7%~105%。
Trace mercury in industrial wastewater was directly determined with DMA-80 automatic mercury analyzer.The experimental condition was optimized such as dry time,decomposition temperature and release temperature.A good linearity was in range from 0 μg/L to 600 μg/L.The detection limit was 5.0×10^-5 mg/L.The RSD of parallel test of industrial wastewater samples was ≤0.2%.The spiked recoveries were between 96.7% and 105%.
