本文通过测定白血病病人血中铜的同位素丰度比,建立一套测试方法作为稳定铜同位素在生物体和示踪技术中的检测手段。在测人体血中铜时,精度好于±0.5%。
In this paper, we established a set of test methods for the determination of copper isotope abundance in patients with leukemia as a means to detect the stability of copper isotopes in organism and tracer technology. In the measurement of human blood copper, the accuracy is better than ± 0.5%.
