concentrations obtained were 4.3 ± 0.2 mg kg1 using the official
method and 4.8 ± 0.3 mg kg1 for the FIA-SD. In the case of biodiesel
from cotton, the values were 5.1 ± 0.6 and 5.8 ± 0.2 mg kg1,
respectively. The values for the samples analyzed, therefore, were
consistent and the phosphorus content was under 10 mg kg1,
which is the amount allowed by ANP Brazilian Agency
