极谱法和原子吸收光谱法快速分析矿石中的锑

建立了用极谱法和原子吸收光谱法测定矿石中含锑量为0.00X%~XX%的锑的快速分析方法,使锑在H2SO4(2%)-HCl(10%)体系中,既可以用极谱法测定,也可用原子吸收光谱法测定,两种方法测锑的定量线性范围均为:0~30μg/mL;检出限(3 N/S):极谱法为0.01μg/mL,原子吸收法为0.1μg/mL。方法加标回收率在98%~110%;相对标准偏差RSD(n=6)在1.5%~5.0%。方法快速简便,高效准确,已用于锑矿的采、选、冶生产过程控制分析,效果良好。

Rapid Analysis of Sb in Ore by Polarographic Method and Atomic Absorption Spectrometry

A rapid analytical method for the determination of Sb in ore,with the contents of Sb from0.00X%to XX%,was established by both polarographic method and atomic absorption spectrometry.The content of Sb could be determined by either of the above-mentioned methods with the linearity ranges 0-30μg/mL in the H2SO4（2%）-HCl（10%）system.The detection limits of polarographic method and atomic absorption spectrometry were 0.01μg/mL and 0.1μg/mL,respectively.The recoveries were in the range of 98%-110%,with the relative standard deviations RSD（n=6）1.5%-5.0%.This method is simple,rapid and accurate,and has been applied to the determination of Sb in mining,mineral and smelting production process control of Sb ore,with satisfactory results.
