中子活化法分析矿石、土壤中稀土元素,用带NaI(Tl)探测器的多道γ谱仪测定时,因其分辨率低,元素之间干扰严重,解谱是比较困难的。但由于NaI(Tl)探测器效率比较高,且目前国内不少多道γ谱仪配备这种探测器。如能找出一种快速有效的分离和富集稀土的方法,对矿石和土壤样品进行前处理,以消除其他元素对稀土元素的干扰,同时再采用较好的解谱方法,尽可能降低稀土元素之间干扰带来的误差的话,利用NaI(Tl)多道γ谱仪分析矿石、土壤中稀土元素,也是一种可取的方法。我们用PMBP柱萃淋法
Neutron activation analysis of ore, soil rare earth elements, with multi-channel gamma spectrometer with NaI (Tl) detector, because of its low resolution, serious interference between elements, the solution spectrum is more difficult. However, due to the high efficiency of the NaI (Tl) detector, many multi-channel gamma spectrometers are equipped with such detectors. If you can find a fast and effective method of separation and enrichment of rare earth, ore and soil samples were pre-treated to eliminate other elements of rare earth elements interference, and then use a better solution spectrum method to minimize rare earth It is also a preferable method to analyze the rare earth elements in ores and soils by using NaI (Tl) multi-channel gamma spectrometer when the error caused by the interference between elements. We use PMBP column extraction method
