作者研制了XPY和XBY两种荧光增强试剂,用于激光荧光法测定地质样品中痕量铀。荧光增强剂不仅对铀有荧光增强作用,而且使测定体系具有较强的抗干扰能力。经验证对岩石样品中的铀的检出下限为0.01ppm。能满足岩石矿物中痕量铀的测定要求。
The authors developed two kinds of fluorescence enhancement reagents, XPY and XBY, for the determination of trace uranium in geological samples by laser fluorescence spectrometry. Fluorescent enhancers not only have fluorescence enhancement of uranium, but also make the determination system have strong anti-interference ability. The lower limit of detection of uranium in rock samples has been verified to be 0.01 ppm. To meet the determination of trace amounts of uranium in rock minerals.
