X射线荧光光谱法测定稀土分量,由于不需要分离成单一稀土元素而优于化学法。测定时主要干扰元素为;铁、锰、钡、铅、镍、钽、铪等。当铁超过50Jg,锰30Jg左右,即严重干扰X射线荧光光谱测定,所以测定含锰铁矿中稀土元素分量,必须预先分 The determination of rare earth components by X-ray fluorescence spectrometry is superior to the chemical method because it does not require separation into a single rare earth element. Determination of the main interference elements; iron, manganese, barium, lead, nickel, tantalum, hafnium and so on. When the iron exceeds 50Jg, about 30Jg of manganese, which seriously interfere with the determination of X-ray fluorescence spectrometry, determination of rare earth elements in manganese-bearing iron ore, must be pre-divided
