本文研究了用磷酸溶样,镍为内标、X荧光法测定钨的条件。克服了粒度、矿物学。基体效应.补偿了仪器漂移的影响。大量Mo,Pb,Zn,Cu,Ca,Mn,Fe等没有干扰。适于测定0.2—80%WO_3的各种类型矿样及液体样品。对含WO_3为5.83%及69.81%的试样,标准偏差分别为0.04和0.17。X荧光仪与电算机联机处理数据。方法快速准确。
In this paper, phosphoric acid solution was used to dissolve nickel and nickel was used as internal standard to determine the conditions of tungsten by X-ray fluorescence spectrometry. Overcoming the particle size, mineralogy. Matrix effect. Compensates for the effects of instrument drift. A large number of Mo, Pb, Zn, Cu, Ca, Mn, Fe and other no interference. Suitable for determination of 0.2-80% WO_3 of various types of mineral and liquid samples. For samples containing WO3 at 5.83% and 69.81%, the standard deviations were 0.04 and 0.17, respectively. X fluorometer and computer online processing of data. Fast and accurate method.
