摘　　要：本文研究了铽(Tb)、钇(Y)、钆(Gd)及它们的混合物对铕(Eu)-噻吩甲酰三氟丙酮(TTA)-氯化甲基三烷基铵(N_(263))-Triton X-100体系的共发光效应,发现稀土离子混合物的共发光效应具有线性加和性,用混合共发光体系不仅能保持单个稀土离子的共发光体系的增敏性,而且抗干扰能力增强,并经过实际样品分析的验证,结果令人满意。The mixture fluorescence enhancement effect was used to decrease the interference from other rare earth ions. Four fluorescence systems, Tb-Eu-thenoyItrifluoroacetone(TTA)-trialkyl ammonium chloride (N263)-Triton X-100, Gd-Eu-TTA-N263-Triton X-100, Y-Eu-TTA-N263-Triton X-100 and [Tb-Gd-Y]-Eu-TTA-N263-Triton X-100,were studied. The mixture fluorescence system not only maintains the high sensitivity of general columinescence system,but also decreases the interference from other rare earth ions.
