摘要
本文研究了铬酸钡沉淀置换－原子吸收光谱法间接测定铁矿、锌精矿中硫时大量共存元素的影响，采用数学校正方法消除大量铁的干扰。建立的方法简便、快速，特征浓度为０．１６μｇ·ｍｌ￣－１／１％，线性浓度范围为０～４０μｇ／ｍｌ。试样分析的结果表明准确度及精密度均符合要求。
An atomic absorption spectrometry for the determination of sulphur in the ironore and zinc concentrates without any prior separation is described. The method is based on the replacement reaction of chromate ion in the barium chrornate with . The sulphur is determined indirectly with the determination of chromate replaced by FAAS. The method is simple, rapid and accurate.
