摘　　要：通过球磨方式将样品制成粉末状,称量后置于150 mL聚四氟乙烯烧杯中,依次加入硝酸、氢氟酸,高氯酸消解。采用电感耦合等离子体发射光谱法测定废渣样品中铝、铁、镁、铅、锌5种元素。通过筛选分析谱线、合理设置背景扣除位置,避免了光谱干扰。方法检出限为0.03~30μg/mL,回收率为97.39%~100%,RSD小于1.6%,具有良好的精确度和准确度,能够满足日常铁钒废渣中杂质元素的分析。The sample was made into powder by ball grinding,weighed and placed in 150 mL teflon beaker,nitric acid,hydrofluoric acid and perchloric acid were added successively,and heated for digestion.Five elements including aluminum,iron,magnesium,lead and zinc were determined by inductively coupled plasma emission spectrometry.Spectral interference was avoided by screening and analyzing spectral lines and setting reasonable background deduction position.The detection limit was 0.03~30 g/mL,the recovery rate was 97.39%~100%,and the RSD was less than 1.6%.
