Abstract: The adjustment of reaction conditions for the detn. by spectrophotometry of microamts. of lanthanides with Arsenazo III was studied. In contrast to literature data, the procedure can be performed in glycine buffers (pH 2.8 ± 0.3) with samples contg. up to 80 μg lanthanide/25 mL. The statistical treatment of the results obtained with std. solns. contg. 4-80 μg lanthanide in 25 mL showed that the std. deviation of the arithmetic mean is 5% and that the relative mean error (e%) is at the same level.
