摘要
用溶剂稀释1,2,4-三氯苯配制氯系列标准工作溶液,建立标准工作曲线,选取中海油15个原油样品,用氧化燃烧离子色谱法、微库仑法、能量色散X射线荧光光谱法进行原油氯含量直接测定,对结果进行比对分析。实验表明,氧化燃烧离子色谱法结果重复性比微库仑法、能量色散X射线荧光光谱法较好,能够减少人为因素带来的误差和其他元素的干扰,可以用于原油氯含量的快速检测。
Dilute 1,2,4-trichlorobenzene with diluent to prepare chlorine series standard working solutions,establish standard curves,select 15 crude oil samples from CNOOC,directly determine the chlorine content of crude oil with microcoulometry,Energy dispersive X-ray fluorescence spectrometry and Combustion-ion chromatography,analyze the results.The experiment shows that the repeatability of the results of oxidation combustion ion chromatography is better than the other two methods,It can reduce the error caused by human factors and the interference of other elements.It can be used for rapid detection of chlorine content in crude oil.
