摘要
研究了由Okamoto腔产生的大功率微波诱导空气等离子体的分析性能以及用该等离子体直接有机溶液进样测定有机溶剂或含有大量有机溶剂的废水中的金属污染物的可行性。用本方法测定了几种工业废水中的金属污染物,并与原子吸收光谱法的测定结果进行了比较。
The analytical performance of a high-powered microwave-induced air plasma generated by an Okamoto cavity at atmospheric pressure and its tolerance to direct organic solvent introduction were investigated. The experimental results showed that this plasma source had a good performance for direct introduction of organic solutions. It could used for direct determination of metal elements in organic samples, organic extracts and wastewater containing high concentration of organic solvents. The method has been used to determine metal pollutants in industrial wastewater, and the results are consistent with those obtained by AAS.
