| 摘 要： | 采用荧光波长色散法测定石油及其产品中氯和溴,通过建立标准曲线,测量几种样品中氯和溴含量。方法的精密度RSD1%,在样品浓度氯和溴含量很低的情况下,氯元素的回收率仍达76.72%~104.78%,溴元素的回收率高达84.22%~101.32%。所以该法可直接取样测定,影响因素较少,适合于快速、准确测定石油及其产品中氯和溴。

| Abstract: | Chlorine and bromine in petroleum and its products were detected by X fluorescence wavelength dispersion method.A standard curve was firstly established,then chlorine and bromine contents in several samples were measured.The results show that the method precision is high,RSD ＜1％;when chlorine and bromine contents are low,the recovery of chlorine is still up to 76.72％ ～ 104.78％,and the recovery of bromine is up to 84.22％ ～ 101.32％.So this method can be directly used to detect petroleum and its products,and it is suitable for fast and accurate determination of chlorine and bromine in petroleum and its products are. |
