高分辨率连续光源原子吸收仪测定矿石中铌、锆含量

Determination of niobium and zirconium in Ores by high resolution continuous source atomic absorption spectrometry

由于传统方法在对矿石中铌、锆含量测定时存在较大的相对标准误差,为此提出高分辨率连续光源原子吸收仪测定矿石中铌、锆含量研究。首先将矿石进行风干、粉碎、消解等处理,对其进行合理制备;然后对TAS-990原子吸收分光光度计进行校正与参数设置,运用该仪器对制备后的矿石中铌、锆电解质浓度进行测量;最后根据测量数计算出矿石中铌、锆含量,以此实现高分辨率连续光源原子吸收仪测定矿石中铌、锆含量。经实验证明,此次设计方法相对标准误差低于传统方法。

Due to the relative standard error of traditional methods in the determination of Nb and Zr in ores,a study on the determination of Nb and Zr in Ores by high-resolution continuous light source AAS is proposed.Firstly,the ore is dried,crushed,digested and prepared reasonably;then the TAS-990 atomic absorption spectrophotometer is calibrated and set with parameters,and the electrolyte concentration of niobium and zirconium in the prepared ore is measured with the instrument;finally,the content of niobium and zirconium in the ore is calculated according to the measurement data,so as to realize the determination of high-resolution continuous light source atomic absorption meter The content of niobium and zirconium in ore.The experimental results show that the relative standard error of the design method is lower than that of the traditional method.
