Determination of Boric Anhydride in Ascharite Ores by Inductively Coupled Plasma Atomic Emission Spectrometry


Article Preview

Inductively coupled plasma atomic emission spectroscopy was applied to the determination of boric anhydride in ascharite ores. Pretreatment method, reagents used for acid decomposition and the interferences from matrix and coexistent elements were discussed in details respectively. The analytical spectral lines were selected while experimental parameters were optimized. The results indicated that after the samples were completely dissolved and collected with hydrochloric acid (1+1) in a sealed container with a reflux condenser by the low-temperature heating method, they could be directly analyzed and determined with ICP-AES at optimized operating parameters. The relative standard deviation of the method is less than 1.4% within the measurement range of 0.1% ~ 40% and the recovery rate is in the range of 98.1% ~ 101.0%. The method was proved satisfactory with wide linear range, low detection limit and also high sensitivity and accuracy.
