Abstract: In this work, a method for the determination of phosphorus in biodiesel (B100) using flow injection anal- ysis with spectrophotometric detection (FIA-SD) is described. Samples were digested using an acid mix-ture in a heating block. The phosphorus concentrations obtained by the (FIA-SD) method were similar to those obtained by the official method. Recovery tests show results between 98.6% and 101.0% for biodie-sel produced from sunflower and between 102.1% and 113.5% for biodiesel produced from castor and soy- beans. The limits of detection (LOD) and quantification (LOQ) obtained using the FIA system were 0.14 mg Lÿ1 and 0.46 mg Lÿ1, respectively.
