| 摘 要： | 在单针进样器的基础上，增加一个三通流路同时进样，在线消解-流动注射分光光度法测定水中挥发酚及氰化物。实验结果表明，挥发酚浓度在0mg/L～0．2mg／L、氰化物浓度在0mg/L～0．5mg／L范围内具有良好的线性关系。通过在线气体扩散分离技术，提高了分析速度，每小时可完成12个～15个样品的分析。方法的相对标准偏差〈5％，回收率在90．4％～108．5％之间。

| Abstract: | The method of simultaneous determination of volatile phenolics and cyanide in water by flow injection analysis is illustrated. The calibration graphs obtained by the method are linear up to 0. 2mg/L of volatile phenolics and 0. 5mg/L of cyanide, A sampling frequency of 12 to 15 samples an hour is readily achieved with in-line through module and gas diffusion separation technology. Volatile phenolics and cyanide are analyzed in water with 3.03% to 8.05% RSD and 90. 4% to 108.5% recovery. The results match those of standard method GB7490-87 and GB7486-87. |
