摘　　要：建立了使用电感耦合等离子发射光谱法测定轻烧镁中硼、磷、硫的方法。试验发现,硼的测定,有良好精密度、线性和检出限,回收率极好;磷的测定,存在"基体增强效应",通过计算校正,提高了测定结果准确性。检出限硼0.0088mg·L^(-1),磷0.052mg·L^(-1),硫0.068mg·L^(-1);回收率硼99.5%~100.2%,磷100.4%~103.5%,硫91.4%~93.9%;精密度硼14.9%,磷11.0%~15.8%,硫9.7%~13.3%。该法是一种快速简便的测定轻烧镁中硼、磷、硫的适用方法。Method for determination of boron, phosphorus and sulfur in light burned magne,,ia by Inductively Coupled Plasma Atomic Emission Spectrometry （ICP-AES）was established. The results showed that it is a method with good precision, linear, and recovery for determination of boron, and calculating correction is used to eliminate the influence of matrix enhancing effect on determination of phosphorus and improve the accuracy. The detection limit was 0.0088mg·L^-1 for boron, 0.052mg·L^-1 for phosphorus, and 0.068mg·L^-1 for sulfur. The recovery was from 99.5% to 100.2% for boron, from 100.4% to 103.5% for phosphorus, and from 91.4% to 93.9% for sulfur. The precision was 14.9% for boron, from 11.0% to 15.8% for phosphorus, and from 9.7% to 13.3% for sulfur. The method was simple and rapid for determination of boron, phosphorus and sulfur in light burned magnesia.
