| 摘 要： | 用高氯酸、硝酸和氢氟酸组成的混酸在加热的条件下消解玻璃纤维滤筒滤膜采集的铅尘样品，可基本除去滤膜中的硅。大部分除去滤筒中的硅，残留的硅酸对铅的溶出和准确测定不干扰。因此是取代索氏提取法和酸煮法的理想方法。

| Abstract: | The air dust collected by glass fiber filter is dissolved with mixture of perchloric acid, nitric acid and hydrofluoric acid, and most silicon in the filter could be removed. The remained silieic acid will not influence the dissolubility of the lead and the accuracy of measurement. It is an ideal method to replace the methods of Soxhlet extraction and acid decoction. |
