火焰光度法测定氧化钠、氧化钾溶剂的改变

A change of the solvent for samples in determination of sodium oxide and potassium oxide with flame photometry

本文通过实验对比,证明用硝酸作为火焰光度法测定氧化钠、氧化钾的溶剂,可延长仪器的使用寿命,保证仪器在使用过程中的稳定性,满足分析要求。

A change of using nitric acid to replace hydrochloric acid as the solvent for samples of“red mud”or“calcined material”has been tested in determination of sodium ox-ide and potassium oxide with flame photometry,with the result of much longer useful life of the flame photometer,assurance of operational,stability,and stable performances of the pho-tometer catering to analytical requirements.
