摘要：

A high accuracy atomic absorption procedure for the determination of lithium is described. The method, which utilizes conventional commercially-available atomic absorption instrumentation, is based on the principle of stable isotope dilution. The procedure is applied to serum lithium determinations and gives an average relative error of about 0.7% for samples in the psychotherapeutic range (5-10 ppm). Analysis time is relatively short since no sample pretreatment is required and the necessity of repeated instrument calibration is eliminated. © 1979, American Chemical Society. All rights reserved.
