摘　　要：本文以SbH_3为例,对氢化物发生-光度分析体系中有机胺溶液消除共价氢化物间干扰的作用进行了探讨。发现SbH_3被有机胺吸收后以Sb(Ⅲ)(～22％)和Sb(V)(～78％)两种形态存在,反应按并伴随与有机胺的络合进行。形态存在,反应按并伴随与有机胺的络合进行。The reaction between the covalent hydrides and the organic amine was studied by the hydride gen-eration-spectrophotometry with SbH3 as the example. The SbH3 absorbed by the amine solution existed ontwo species of Sb(Ⅴ)(-78%)and Sb(Ⅲ)(-22%). The mechanism of the reactions by SbH3 series and the complexes formation between Sb(Ⅱ),Sb(Ⅴ)and organic amine was proposed.
