摘要：

A new sorbent, Ekosorb, has been developed and tested. It is prepared on the basis of a modified silica gel and warrants perfect purification of food extracts from fats and other co-extract substances. The pure eluate is suitable for trace analysis of polychlorinated aromatic compounds (polychlorinated biphenyls, hexachlorobenzene), chlorinated pesticides etc. Recovery of residues of chlorinated compounds is higher than 96%, allowing a quantitative determination and detection by gas chromatography. Ekosorb is an equivalent to Florisil.
