摘要
如何从黄砂中快速而有效地提取金和铂一直是研究人员比较关心的课题。运用X射线荧光光谱法分析黄砂中的金和铂含量是当前比较灵敏、快捷的一种分析方法。样品经充分研磨和干燥后,以硼酸盐为熔剂,在一定温度下熔融制片,利用_UQ测定程序和晶体LiF200,调节X射线荧光光谱仪分析参数,确定了黄砂中金和铂含量的最佳测定条件,对黄砂中金和铂的提取具有现实指导意义。实验表明:样品干燥时间在4 h以上,然后以四硼酸锂为熔剂,熔样制片温度控制在1100℃时,测得金和铂含量最稳定,其质量分数分别为0.243%和0.174%。
All the way, how to make gold and platinum extract from sand quickly and effectively is more concerned for research workers. At present, percentages determination of gold and platinum in sand by X - ray fluorescence analysis was one of the sensitive and quick methods. At a suitable temperature, a piece of crystal was obtained in flux of borate, after the sample grinded and dried. The optimum conditions of percentages determination of gold and platinum in sand have been confirmed by adjusting parameters of X - ray fluorescence instrument and using measuring program _UQ and a piece of crystal LiF200. Realistically, it has directive sense for extraction of gold and platinum in sand. The test indicates ： if the time of drying samples is more than 4 h,taking lithium tetraborate as flux,and temperature of melting samples controls at 1 100 ℃, the most stable percentages of gold and platinum can be determined,which are 0.243% and 0. 174% respectively.
