KINETIC DETERMINATION OF BERYLLIUM USING DECOMPOSITION OF ITS COMPLEX WITH CHLOROPHOSPHONAZO R

Elena I Danilina, Yulia V Akatieva

Аннотация


Fast decomposition of beryllium complex with Chlorophosphonazo R in the absence of acetylacetone can be used for its kinetic determination by the tangent method. Analysis time drops from 30 min to 2 min. Optimal conditions and metrological characteristics of the procedure have been found. In the presence of EDTA selectivity, precision and sensitivity increase. The lower limit of concentration range is 0.15 µg/mL, the relative error does not exceed 2 %, while the observed errors of reproducibility are less than 3.3%. Selectivity factors for a number of interfering cations and anions have been determined.
