本文详细研究了铕-钇-二苯甲酰甲烷(DBM)-二苯胍(DPG)-丙酮体系的共发光效应,在最佳实验条件下,Eu~(3+)在1.0×10~(-10)～5.0×10~(-8)mol/L浓度范围内与荧光强度成线性关系,检测限达5.0×10~(-13)mol/L。用多点增量标准加入法测定了合成样品中的铕结果满意。
In this paper, we studied in detail the co-luminescent effect of europium-yttrium-dibenzoylmethane (DBM) -benzophenone (DPG) -acetone system under the optimum conditions. -10) ~ 5.0 × 10 ~ (-8) mol / L, the detection limit was 5.0 × 10 ~ (-13) mol / L. The results of the determination of europium in the synthesized samples by multi-point incremental standard addition method were satisfactory.
