摘　　要：研究用Y( )与邻苯二酚紫、1,10-邻菲罗啉及溴化十六烷基三甲铵所形成络合体系和N2O-C2H2火焰原子吸收光谱法测定稀土矿中的钇。在pH9.0的NH3·H2O-NH4Cl缓冲底液中,Y( )的浓度在0.20～2.1μg/mL间与吸光度成正比。本法用于稀土矿中的钇的测定,结果满意。It has been investigated that determination of Y in rare earth ores by Y(PV)_2 (phen)_(10) (CTMAB)_6 and FAAS with N_2O-C_2H_2 flame. The liear relationship between absorbance and concentration of Y exists in the concentration range of 0.20~2.1μg/mL for Y in NH_3·H_2O-NH_4Cl bufler solution at pH9.0. The method has been applied to the determination of trace Y in rare earth ores with satisfactory results.
