提出了新型差减法测定原油有机氯含量的分析方法。通过对原油无机氯化物萃取实验条件的优化，进行了有机氯的加标回收实验。结果表明：所述方法用于测定原油有机氯含量切实可行，既克服了 GB∕T 18612方法的局限性，也较好地解决了常规差减法测定结果可靠性差的问题。%A new subtraction method for determination of the organic chlorine content in crude oils was proposed. The spiked recovery test was conducted under the optimized extraction conditions for in-organic chlorides in crude oils. The experiment results indicate that the given method is feasible for de-termination of organic chlorine content in crude oils. It not only avoids the limitations of GB∕T 18612, but also better solves the problem of poor reliability in the existing subtraction method.
