Method for determining tributyl phosphate and / or butanol by liquid chromatography

摘要

The invention relates to the determination of tributyl phosphate (TBP) and / or butanol by liquid chromatography. BR/ A sample of an organic solution comprising TBP and / or butanol is injected into a column (1) filled with a polar solid stationary phase, for example of silica grafted with NH 2 groups, and covered by a mobile liquid phase of apolar nature, for example a mixture of heptane and ethyl acetate, from (9) and the TBP and / or butanol leaving the column is detected by refractometry in (11). / P
