摘要
原子吸收法测定矿石中0.05~X%的锑已有报道,但原子吸收法测矿石中高含量锑,尚未见报道。本文以盐酸、硝酸分解样品,用柠檬酸防止在盐酸溶矿时锑以三氯化锑形式挥发和锑的水解。在空气一乙炔火焰中,用锑的次灵敏线231.2nm测定0.x~60%的锑。用拟定的方法测锑时速度快,选择性高,重现性好,砷及大多数元素不干扰测定。
A study of flame AAS determination of 0.x-60% antimony in ores and minerals has been worked out. Citric acid is used to prevent the volatilization and hydrolysis of antimony. Determining at 231.2nm line gives reproducible and accurate results.
