Abstract:
      In this paper, a method for the determination of B2O3 in tourmaline by inductively coupled plasma-atomic emission spectrometry (ICP-OES) with hydrothermal acid-nitric-acid-phosphoric acid-perchloric acid system was established. The limit ofdetection (LoD) was 0.096 mg/L, the relative standard deviation (RSD) was 0.37% and the recovery percentage was 97.2% – 102%. The described method is simple, highly precise, with good accuracy and applicability for large numberof samples, hence, is of a practical significance.
