Abstract:

Trace amounts of dibenzb,f1,4 oxazepine may be estimated by either a colorimetric or an ultraviolet spectrophotometric procedure. The colorimetric procedure gives an average recovery of 99.9 with a best estimate standard deviation of 1.0. The minimum detection concentration is 0.3 micrograms in a 5.0-ml reaction volume with a calculated double-tail 95 confidence interval for the population of 97.5 to 102.3. The UV-spectrophotometric procedure gives an average recovery of 100.0 with a best estimate standard deviation of 0.7. The minimum detection concentration is 0.2 micrograms per milliliter of solvent with a calculated double-tail 95 confidence interval of 98.4 to 101.6. Procedural requirements are given and discussed. An extraction technique is given to minimize potential interference in the colorimetric procedure. Both methods involve uncommon chemical species. Either separately or in combination, the methods readily lend themselves to the identification and detection of dibenzoxazepine in thin-layer chromatographic procedure. Author
