[Purification of extracts from biological material using aluminum oxide].
An effective, rapid, and safe operation is suggested for purification of extracts from biological material from co-extractive substances during testing for barbiturates, benzophenones, and nichlofolane. The purification is carried out on a column packed with aluminum oxide.
