Descrição geral

Diisooctylthiophosphinic acid (Bis(2,4,4-trimethylpentyl)thiophosphinic acid) is a hygroscopic liquid. Its physical properties (refractive index and specific gravity) have been reported.
Diisooctylthiophosphinic acid is an application specific reagent.

Aplicação

Complexing agent for the extraction of transition metals
Diisooctylthiophosphinic acid is suitable for use in the colorimetric determination of airborne lead. It may be used as chelating agent for supercritical fluid extraction (SFE) of metals, for subsequent ICP-MS analyses of mercury, cadmium and lead in sediment.
