摘要
用电感耦合等离子发射光谱法 (ICP AES)测定渣油中金属元素铁、镍、钙、镁、钠、钒 ,考察了不同的酸浓度对分析结果的影响和共存元素间的相互干扰 ,进行了加标回收率和精密度试验。
Ferrum, nickel, calcium, magnesium, sodium and vanadium in residual oils were determined by inductively coupled plasma emission spectroscopy. The effects of various concentrations of acid solution on analysis results, the interaction of coexisted elements, standard addition recovery, and precision of the method were investigated.
