title: [The maximum adsorptive capacities of three activated carbons produced in the GDR for barbiturates, other hypnotics and tranquilizers from aqueous and low-percentage ethanolic solutions (author's transl)].
abstract: A standardized stirred-batch experiment has been performed to determine the maximum adsorptive capacities of three activated carbons (R4, ASO and walnut coal) produced in the GDR for acetylsalicylic acid, methylsalicylate, phenobarbital, crotylbarbital, hexobarbital, pentobarbital, glutethimide, chlorophenethazine and methaqualone from aqueous and low-percentage ethanolic solutions. The activated carbon ASO and the walnut coal have always been found to be markedly superior to the activeated coal R 4. The maximum adsorptive capacities so far determined compare with data on activated carbons produced abroad, so that further developmental work seems worthwhile.20
