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RSD<1%,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。
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.
