一、4,5-二羟基-萤光黄可用作Sb(Ⅲ)的定性检定试剂。灵敏度为0.3γ(1:166,000)。只有Fe(Ⅲ),Ba(Ⅱ),Pb(Ⅱ)干扰,Sn(Ⅱ)虽有呈色反应,但不干扰。二、4,5-二羟基-萤光黄与Sb(Ⅲ)的反应生成颜色的强度符合比尔-兰伯特定律。生成的悬浮物稳定,所以可用作Sb(Ⅲ)的比色试剂。

Gallein has been found to be an excellent reagent for antimonous ions. Its 0.05% aqueous solution gives a violet-red coloration or precipitate with the latter.
