Testing human hair for drugs of abuse. III. Identification of heroin and 6-acetylmorphine as indicators of heroin use.

abstract：:Six separate methods to detect oxidants in urine were developed. The presence of the oxidants was established by initial oxidation of ferrous to ferric ion and detecting the ferric by chromogenic oxidation or complex formation. The reagents for chromogenic oxidation were N,N-dimethylamoino-1,4-phenylenediamine (DMPDA)...
