DETERMINATION OF BERYLLIUM IN BIOMATERIALS AND NATURAL WATER (in Japanese)

Journal Article · · Bunseki Kagaku (Japan)
In order to apply the spectrophotometric acetylacetonate method to the deterniination of beryllium in sea water, lake water samples and biomaterials, the procedures for the concentration of trace amount of the element, the ashing of the samples, and the removal of the disturbing phosphate were studied. As the decomposition of biomaterials, the dry method was examined, and the ashing at 600 deg C was found to be the best. Beryllium was not lost on this condition. The coprecipitation with ferric hydroxide was used tor the concentration of beryllium. Beryllium was quantitatively recovered when the precipitation was carried at pH 7. Phosphate gave a negative error in the determination of beryllium, and so must be removed. The ferric hydroxide coprecipitation method can be used also for the separation of beryllium from phosphate, and it seemed to be better than the ammonium phosphomolybdate procedure. When ferric hydroxide precipitated at pH 11, in the presence of EDTA, beryllium coprecipitated, while phosphate did not contaminate even when calcium was present as in the biomaterials. The analytical procedures are described. Sea water, lake water samples and several biomaterials such as seaweed were analyzed. (P.C.H.)
