摘 要: | 为寻找有效且简单的克服基体效应的方法,我们研究了树脂吸附铀的行为:742阴离子树脂具有孔径大,吸附洗脱快等优点,本文择其吸附快之长处,对少量粉末状742树脂(280目以上)吸附铀的可能性进行了探索试验,富集分离效果良好。最终拟定在硫酸介质中以742阴离子树脂静态吸附分离铀,X-射线测量的方法,操作简单易行,方法灵敏度高、稳定。适应于地质、选冶样品中0.00X~X%

Determination of Uranium in Ores and Samples of Mineral dressing and Metallurgy by XRF Spectrometry |
| |
Abstract: | In sulfuric acid medium at pH 2-3,uranium can be sorbed by 30mg of Type-742 anion resin (250-400) in competing eqilibrious sorption. Then the resinand the sorbed uranium is filtered on a circular paper. Intensity is measuredby VRAXRF-spectrograph using a x-ray tube with a Mo anode at 50 KV, ULa I ray and a LiF crystal analyser The method has been used for determination of uranium (0.00X-X%) inores and samples of mineral-dressing and metallurgy. |
