电感耦合等离子体原子发射光谱法在润滑油杂质元素分析中的应用

Application of inductively coupled plasma-atomic emission spectrometry for analysis of impurity elements in lubricating oil

试述了电感耦合等离子体原子发射光谱法测定润滑油中杂质元素的样品前处理方法———无机处理法和有机进样法;对影响测定结果的相关因素,如仪器工作条件、干扰及校正、处理样品的酸及其浓度、有机进样等进行了讨论。

A review was presented on the sample pretreatment techniques of the analysis of impurity ele- ments in lubricating oil by ICP-AES, including inorganic treatment methods and organic solvent sampling methods. Some involved factors influencing ICP-AES determination results, such as working conditions of instrument, interference and calibration, acid for treatment of sample and its concentration, organic solvent sampling and so on, were discussed.
