【Abstract】 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.更多还原
