Determination of copper and molybdenum in the hard dental tissues of rats by atomic-absorption spectrophotometry.
The measurement of uptake of copper and molybdenum from the diet into rat's teeth required the use of an accurate but rapid method of analysis. The simultaneous extraction of copper and molybdenum with APDC from the sample, combined with atomic absorption, proved to be both accurate and reliable. Interference from other elements present in the sample was easily overcome by the use of standards with a matrix equivalent to that of the teeth.
