摘　　要：本文研究了在紫外光区吐温 - 80水溶液中硫氰酸钴 ( )配合物摩尔吸光系数 ,得到最大吸收波长λmax=32 1nm处摩尔吸光系数为 9.730× 10 3L·mol-1·cm-1。研究发现 ,在吐温 - 80水溶液中硫氰酸钴 ( )形成一种新的三元配合物 。The molar absorption coefficients of cobalt(Ⅱ) thiocyanate complexes in the tween 80 aqueous solution within UV spectrum were studied.It was got that the molar absorption coefficient is 9.730×10 3L·mol -1 ·cm -1 at the maximum absorption wavelength λ max =321nm.A new triadic complexes was formed by the cobalt(Ⅱ) thiocyanate complexes in the tween 80 aqueous solution,which can declare the reason why the reaction is so sensitive.
