本文研究了吐温－８０水溶液中硫氰酸铋（Ⅲ）配合物的吸收光谱，最大吸收波长λｍａｘ＝３３５ｎｍ，其摩尔吸光系数ε３３５＝２．６１×１０４，与ＰＡＲ、偶氮胂（Ⅲ）与铋（Ⅲ）的配合物的ε６１０＝２．７０×１０４相近。发现形成一种新的三元配合物，并用来解释在吐温－８０水溶液中硫氰酸铋为一种灵敏的显色反应。
In this paper, the absorption spectra of bismuth thiocyanate (Ⅲ) complexes in Tween-80 aqueous solution were studied. The maximum absorption wavelength λmax = 335nm, the molar absorptivity ε335 = 2.61 × 104, And bismuth (Ⅲ) complexes of ε610 = 2.70 × 104 similar. A new ternary complex was found and was used to explain the sensitive chromogenic reaction of bismuth thiocyanate in an aqueous solution of Tween-80.
