摘要：

Supercritical fluid extraction (SFE) was used for the isolation of antioxidant aromatic amines from tyre rubber. The efficiency of SFE was comparable with that of Soxhlet microextraction. Aromatic amines were also extracted from different matrices (inert silanized material, sand and humic soil) with supercritical carbon dioxide. It was found that the extraction efficiency depends on the nature of the matrix. Whereas the recovery of amines from the inert material approached 100%, that from acidic matrices was poor and some amines were not recovered.
