摘　　要：研究了在溴化十六烷基三甲基铵(CTMAB)的存在下,溴代苯基荧光酮(BPF)与锗和锌反应分别形成稳定的络合物,可用来同时测定Ge4+和Zn2+。锗和锌络合物的最大吸收波长分别在540和565 nm处,摩尔吸光系数分别为1.66×105和4.35×104L.mol-1.cm-1。并利用k系数法进行校正避免Ge4+和Zn2+之间的干扰,用于人体血浆中锗、锌的测定。A simultaneous determination method of Germanium and Znic by bromophenylfluorone reacting with germanium and zinc to form stable complexes in the presence of CTMAB was studied. The maximum absorption wavelengths of germanium and zinc complexes are 540 and 565 nm, respectively. The molar absorptivities of germanium and zinc complexes are 1.66×10^5 and 4.35×10^4 L·mol^-1·cm^-1, respectively. It is satisfactory to determine germanium and zinc in plasma of human body by correcting method with K factor to aviod the disturbance between germanium and zinc.
