title: [Study on the molar absorption coefficients of Bi(III)-thiocyanate complexes in UV spectrum].
abstract: The absorption spectra of bismuth(II)-thiocyanate in the Tween-80-H2O solution were studied in this paper, in which the maximum wavelength lambdamax = 335 nm and the molar extinction coefficient epsilon335 = 2.61 x 10(4), similar to those of complexes of bismuth with PAR or azoarsenic(III), epsilon610 = 2.70 x 10(4). A new tribasic complex was found and used to explain that bismuth(III)-thiocyanate is a sensitive colour reaction in the Tween-80-H2O solution.
