We have studied the composition of the complex, the molar extinctioncoefficient and absorbance of wavelength of a ternary (UO_2~(2+), BPR, Ca-tionic surfactant) and quaternary(UO_2~(2+), BPR, Cationic surfactant, Nonio-nic surfactant) system.

• 我们研究了三元体系(UO_2~(2+),BPR,阳离子表面活性剂)和四元体系(UO_2~(2+),BPR,阳离子表面活性剂,非离子表面活性剂)的络合物组成、摩尔吸收系数和吸收波长。
