Abstract
New methods utilizing the adsorptive nature of charcoal were proposed for the detection of very small amount of morphine in urine. The advantages of the methods are (a) simplicity, i.e., no particular apparatus, reagents and compounds nor special technic are necessary throughout the procedures (b) sensitivity, 50μg of morphine in 50ml of urine can be detected by simple procedure and 10μg of morphine in 100ml of urine are detectable by standard procedure (c) rapidity, treatment of six urine samples is completed in 120 minutes by simple procedure and 180 minutes by standard procedure. These advantages may satisfy, the demands depending on their aims from field workers as well as from laboratory investigators.
