Notizen: Abstract Diffusion coefficients of the electron acceptor dye tetrazolium blue were measured by the Taylor dispersion method, with an accuracy better than 4%, in two solvents: (i) a homogeneous one-aqueous phosphate buffer, 0.1 M, pH=7.0 (medium I); and (ii) a heterogeneous one-nonionic micelles of Triton X-100, 2.0 mM (where M stands for mol·dm−3), in the same aqueous phosphate buffer (medium II). The values obtained were D 12 I =3.64×10−10m2·s−1 and D 12 II =3.01×10−10m2·s−1·D 12 II has the meaning of a “macroscopird or “average” diffusion coefficient, in which the partition coefficient of tetrazolium blue between micelles and water, as well as the diffusion coefficients of this dye and of the micelles in the aqueous phase, are involved.
