Description

A analysis method for determination of sulphuric acid radical in diuranate by barium sulfate nephelometery was studied. The experimental results show that the linear correlation coefficient (r) > 0.997 when concentration of sulphuric acid radical was in the range of 16 to 40 μg/mL. The detection limit of the method was 0.4% when sample quantity was 0.5 g, and the recovery was in the range of 90.7% to 105%. RSD was 2.8% when concentration of sulphuric acid radical was 5.72%. 0.4 mg of fluorin and 10 mg of calcium did not interfere with determination of sulphuric acid radical. (authors)
