锗及其化合物具有多种生物活性,它能增强机体免疫功能和延缓细胞衰老。因此,锗的测定对人体健康长寿和疾病防治具有重要意义。由于锗在高温下会形成挥发性的一氧化锗而损失,故给锗测定带来很大困难。本文采用CCl_4—水反萃取法消除共存干扰元素,在国内首次采用H_2P_tCl_6.6H_2O—Ni(NO_3)_2混合基体
Germanium and its compounds have a variety of biological activity, it can enhance the body’s immune function and delay cell senescence. Therefore, the determination of germanium on human health and longevity and prevention and treatment of disease is of great significance. As germanium forms volatile germanium oxide at high temperature, it will be very difficult to determine germanium. In this paper, the use of CCl 4-water stripping extraction of interference elements to eliminate coexistence, the first time in China using H_2P_tCl_6.6H_2O-Ni (NO_3) _2 mixed matrix
