研究了镧，钐，钕，镱，铒分别对钪的增感作用。用大量的镧作为增感试剂和化学干扰抑制剂，并引入了双波长（６０７．９ｎｍ和６０７．６ｎｍ）差示法克服光谱干扰，对钪单氧化物蒸气发射光谱法测定钪进行了研究。测定了人工合成混合稀土氧化物样品中的钪，获得满意结果。
The sensitization effects of lanthanum, samarium, neodymium, ytterbium and erbium on scandium were studied. A large amount of lanthanum was used as sensitizing agent and chemical interference inhibitor. The dual wavelength (607.9nm and 607.6nm) differential method was introduced to overcome the spectral interference and scandium was studied by scandium monoxide vapor emission spectrometry. The scandium in the synthetic rare earth oxide samples was measured and satisfactory results were obtained.
