摘　　要：[目的]探讨采用盐酸-硝酸-高氯酸消解-原子吸收法测定垃圾中Pb、Cu、Mn含量的方法。[方法]采用硝酸-盐酸-高氯酸消解垃圾样品,并用火焰原子吸收分光光度法测定遵义市垃圾中Pb、Cu、Mn的含量。[结果]垃圾中Pb、Cu、Mn的含量均比黄土中的含量高,相对标准偏差均小于2.0%。以硝酸-盐酸-高氯酸消解垃圾样品,火焰原子吸收分光光度法测定样品中的Pb、Cu、Mn的含量,无论在时间上、程序上都要简单方便,适合大批量样品多种元素的测定。该方法准确、快速、简便,用于垃圾中Pb、Cu、Mn含量的测定,结果令人满意。[结论]以硝酸-盐酸-高氯酸消解垃圾样品,火焰原子吸收分光光度法测定样品中的Pb、Cu、Mn含量的方法可行。[ Objective ] The testing method of the content of Pb, Cu and Mn in garbage with the hydrochloric acid-nitric acid-perchloric acid digestion was explored. [Method] The samples of refuse were digested by the nitric acid-hydrochloric acid-perchloric acid and the content of Pb, Cu and Mn in garbage in Zunyi City was determined with the flame atomic absorption spectrophotometric method. [ Results ] The content of Pb, Cu, Mn in garbage was more than that in the loess and the relative standard deviation was less than 2.0%. The method was simple, convenient and suitable for the determination for a variety of samples and a large amount in both time-consuming and procedure. The test result from the method was satisfied. [ Conclusion] It was feasible to digest samples of refuse with nitric acid-hydrochloric acid-perchloric acid ion and to determine the content of Pb, Cu and Mn with the flame atomic absorption spectrophotometric method.
