A.2 Principle The sample is dissolved in hydrochloric acid. The boron content is determined by the standard working curve method on an inductively coupled plasma atomic emission spectrometer. A.3 Reagents or materials Unless otherwise specified, only reagents confirmed to be of superior purity are used in the analysis. Boron-containing vessels shall be avoided during the experiment. A.3.1 Water, GB/T 6682, grade 2. A.3.2 Hydrochloric acid (ρ = 1.19 g/mL). A.3.3 Hydrochloric acid (1 + 1). A.3.4 Boric acid (99.99%), spectrally pure.
