摘　　要：通过试验对比分析,研究了油田含油污泥中8种重金属测定的前处理方法。得出适用于油田含油污泥样品中不同重金属元素检测时的前处理方法。分析结果表明,对检测Zn、Cd元素,HNO_(3)-H_(2)O_(2)法、HCl-H_(2)O_(2)法、王水法三种前处理消解效果较好,其中HCl-H_(2)O_(2)法消解效果最佳;对测定Ni、Cr元素,固废法为最佳前处理方法,对测定Ba元素,HNO_(3)-H_(2)O_(2)-HClO_(4)法消解效果最佳;对测定Be元素,固废法、王水-H_(2)O_(2)法、HNO_(3)-H_(2)O_(2)-HClO_(4)法、HCl-H_(2)O_(2)法、王水法消解效果相同;对检测Pb元素,王水-H_(2)O_(2)法消解效果最优;对测定Cu元素,王水法消解效果最好。The pretreatment methods for the determination of 8 heavy metal elementsin oily sludge from oilfields were studied.Through experimental comparative analysis,the pretreatment methods applicable for the detection of differentheavy metalelements in oily sludge samples from oilfields were obtained.For detection of Zn and Cd elements,HNO_(3)-H_(2)O_(2),HCl-H_(2)O_(2),and aqua regia methods showed good digestion effects,with HCl-H_(2)O_(2) method exhibiting the best digestion effect.For the determination of Ni and Cr elements,solid waste method was the optimal pretreatment method.For the determination of Ba element,HNO_(3)-H_(2)O_(2)-HClO_(4) method had the best digestion effect.For the determination of Be element,the digestion effects of solid waste method,aqua regia-H_(2)O_(2) method,HNO_(3)-H_(2)O_(2)-HClO_(4) method,HCl-H_(2)O_(2) method,and aqua regia method were the same.For detection of Pb element,aqua regia-H_(2)O_(2) method had the best digestion effect.For the determination of Cu element,the aqua regia method exhibited the best digestion effect.
