摘要:
Ethylmorphine, morphine, codeine, cocaine, sernyl (PCP), LSD, 3-quinuclidinyl benzilate (BZ) provide, together with Cresol Red, ion-associates that are extractable by chloroform. The extracts of the ion-associates prove the absorption maxima in the interval 405 to 415 nm. Maximum extraction of the analytes of the ion-associates is reached after 4 minutes, taking readings of different pH values in 4 intervals of 1.5. This method allows detect of alkaloids and synthetical psychopharmaca row of quantities between 0.45 μg.ml−1and 1.55 μg.ml−1and to determine 1.05 μg.ml−1to the amount 2.99 μg.ml−1of the analytes in the aqueous solutions.
