| 中文摘要 |
| 在计算机上运用自编程序绘出苯胺的三维荧光光谱,确定苯胺的特征荧光峰,提出了三维荧光光谱法测定苯胺的分析方法。苯胺浓度在2.0×10-7—5.0×10-6mol/L范围内与相对荧光强度呈良好的线性关系。该法相对标准偏差为2.5%,检出限为1.0×10-7mol/L。用于工业废水中苯胺的测定,结果令人满意。 |
| 英文摘要 |
| The diagram of the tridimensional fluorescent spectrum (TDFS) of aniline was given by using an authors-developed program SIMS (serface image maker system) on a computer. The characteristic peak of aniline was defined. A new method for the determination of aniline by TDFS was suggested. When the concentration was in the range of 2.0×10-7—5.6×10-6 mol/L, a fine linear relationship between aniline concentration and relative fluorescence intensity was shown. The R. D. S. was 2.5%. The detection limit was 1.0×10-7 mol/L. With the method,aniline in polluted water from industry was determined satisfactorily. |
