电感耦合等离子体发射光谱(ICP-OES)法测定电气石中的B_2O_3

Determination of B_2O_3 in Tourmaline by Inductively Coupled Plasma-optical Emission Spectrometry(ICP-OES)

建立了氢氟酸-硝酸-磷酸-高氯酸体系密闭溶矿,电感耦合等离子体发射光谱(ICP-OES)法测定电气石中B_2O_3的方法。实验表明,方法的检出限为0.096mg/L,相对标准偏差(RSD)为0.38%,加标回收率为97.2%~102%。方法流程简单,精密度高,准确度好,可进行批量样品的分析测定,具有实际应用意义。

In this paper, a method for the determination of BzO3 in tourmaline by inductively coupled plasma-optical emission spectrometry （ICP-OES） with hydrothermal acid-nitric-acid-phosphoric acid- perchloric acid system was established. The limit of detection （LoD） was 0.096 mg/L, the relative standard deviation （RSD） was 0.38% 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 oractical significance.
