阐述了用全谱ICP—OES测定二次精制盐水中碘含量的实验条件及准确性，比较了在用ICP—OES测量碘时采用生成挥发物进样技术和普通液体进样技术的2种方法，探讨了采用普通液体进样技术的仪器配置要求、气流参数和高频发生器功率的选择、碘测定谱线的选择等。最后用优化好的条件进行二次盐水中碘含量的测定，并通过实验验证了方法的可行性和稳定性。该法解决了传统方法检验时间长、准确性差的问题。

Determination of iodine contained in secondary brine by ICP-OES

The experimental conditions and accuracy of determining iodine content of secondary refined brine by full spectrum ICP-OES were introduced. The sample injection method with volatile resultant and that with common solution were compared in the determination of iodine content by ICP-OES. The re- quirement of instrument configuration, the selection of gas flow parameter and power of high frequency generator, and the selection of spectral line for iodine determination were discussed when adopting the sample injection method with common solution. The iodine content of secondary brine was determined un- der the optimized conditions. The feasibility and stability of the method was verified by experiments. The problems such as long determination period and poor accuracy in traditional methods were solved by the method.
