摘要
将电感耦合等离子体原子发射光谱法应用于钼矿石的物相分析,并对总钼及对不同的物相的前处理方法作了详细的叙述。选择波长为204.5 nm的谱线作为分析线。方法的检出限（3s）为0.008 mg·L-1。该方法用于3种钼矿样品中的物相分析,所得结果与比色法的测定结果相符,测定值的相对标准偏差（n=11）在0.5%-3.6%之间。
ICP-AES was applied to phase analysis of molybdenum ores. Different procedures were proposed and described in detail for the determination of total molybdenum and various phases of the molybdenum ores. The spectrum of 204. 5 nm was chosen as the analytical line. Detection limit （3s） of the method was found to be 0. 008 mg. L-1. The proposed method was used in the phase analysis of 3 ore samples, giving results in consistency with the results obtained by the photometric methods. Values of RSD＇s （n= 11） found were in the range of o. 5%-3.6%.
