摘要
Two different sample pretreatment methods-NaOH alkali fusion method and HCl-HNO3-HF-HClO4 acid dissolution method were compared in order to quantify Ga in bauxite ore samples by inductively coupled plasma-atomic emission spectrometry (ICP-AES). The loaded reagents, chemical procedure, selection of analysis spectral lines and interferences are discussed in this paper. National Standard Reference bauxite ore samples with different Ga contents were analyzed by using both sample pretreatment methods. This method has advantages of rapid analysis, simple operation and more efficient measurement of Ga in bauxite ore samples.
