摘　　要：本文在共价氢化物发生-光度分析体系中设置固体氧化剂氢化物气体分离柱,以AsH_3、SbH_3和SnH_4为研究对象探讨了氢化物之间的干扰消除及高选择性测定问题。成功地建立了锡测定时其它共价氢化物元素干扰的消除方法,具有简便、高效、实用的特点。With the solid oxidizer covalent hydrides separation column, the elimination of interference among different hydrides and their highly selective determination were discussed by the system of hydride generation-spectrophotometry with AsH_3, SbH_3 and SnH_4 as the examples. The highly selective determination of tin, where the interferences from other covalent hydrides has been eliminated, was established with simple, efficient and ap- plicable characteristics.
