矾土中钾、钠、硅、铁、钙、镁、钛的ICP-AES测定

Determinaton of K,Na,Si,Fe,Ca,Mg and Ti in Bauxite by Inductively Coupled Plasma Atomic Emission Spectrometry

以碳酸锂-四硼酸锂为熔剂,铝矾土试样经高频融样机高温熔融。熔融物在PTFE烧杯中,用稀盐酸加热溶解。样品溶液使用电感耦合等离子体原子发射光谱仪测定,结果准确度高、重复性好。

Using lithium carbonate-lithium tetraborate as the flux,the sample of bauxite was melt with high temperature by HMST-I-MXZ,and the cooled fusant was dissolved by the heateddilute hydrochloric acid in PTFE beaker.The sample solution was measured by ICP-OES.The measurement can got high accuracy and repeatability.
