摘要
建立了电感耦合等离子体发射光谱法同时测定钼矿石中钼、铜、铅、钨、钛、硫6中元素含量的分析方法。采用微波消解溶解样品，在选定的仪器工作条件下直接测定。通过试验确定了各元素的分析谱线，对试液的酸度进行了探讨。6种元素的检出限为0．042～0．612／g／ml，加标回收率为97．01％-μ101．59％，测定结果的相对标准偏差0．89％-3．56％（n=6）．该方法灵敏度高，适用于钼矿石中多种元素的同时测定。
The analysis method was established for simultaneous determination of 6 elements in the content of molybdenum ore molybdenum, copper, lead, tungsten, titanium, sulfur by ICP-AESo The sample was dissolved by microwave digestion, Direct determination of under the selected experimental conditions Analysis of the elements of the spectral line was determined by experiment On the acidity of the sample solution were discussed SIX elements in the detection limit is 0.042-0.612 μg/ml, The recovery was 97.01%-101.59%, The relative standard deviation of the determination results of （ n=6 ） 0.89%-3.56%. The method of high sensitivity and Applicable to a variety of elements in the determination of molybdenum ore
