The Difference

Abstract Mercury in biological samples is determined by digestion in nitric acid, sulfuric acid, and permanganate, followed by reduction and aeration for measurement by atomic absorption at room temperature. The average recovery is 95.8% with a standard deviation of 13.3%. The standard deviation, calculated from the difference between duplicates of 23 samples, is 0.063 μg mercury, which represents 9.4% of the average value of the samples. The method is simple and requires approximately 4 hr for completion. Mercury can be confirmed by adsorption on gold foil after maximum absorbance has been obtained during aeration.

SummaryA new procedure is described for separating radiopotassium in the form of the Perchlorate in neutron activation analysis of biological samples. Compared to the classic procedure used in gravimetry (evaporation with HClO4 to a small volume) precipitation with 20% HClO4 at room temperature is used. The product thus obtained is radiochemically purer, and the separation is more rapid than in the classic procedure. An optimum of the sodium holdback carrier concentration has been found. The method described has been used to determine potassium in blood samples.
