| Abstract: | 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. |
