工业废水中钡的排放限值研究

Study on Emission Limits for Barium in Industrial Wastewater

在查阅大量文献资料基础上,总结了环境中钡的来源和特性,采用电感耦合等离子原子发射光谱方法测定地表水及稀土废水中的钡元素含量。对仪器的工作参数和被测元素的分析谱线进行了优化和选择,结合钡的化学毒性,提出了废水中钡的标准是5mg/L的建议。

Based on consultation of literature,sources and features of Barium were summarized and the ICP-AES and other means were applied to determine Barium in surface water and rare-earth industrial wastewater.Working condition of the instrument and analytical spectral lines for the elements were tested and optimized.According to the toxicity of Barium,we propose that concentration standard for Barium in wastewater should be 5 mg/L.
