Table 1

Apparent diffusion coefficient (𝐷_app) of I₃⁻ in solutions A~D.

Solution	10^−7𝐷app (I3^−)/(cm^2·s^−1)
(A) m(HEEDAI) : m(MPII) = 1 : 9	5.0
(B) m(HEPI) : m(MPII) = 1 : 9	4.4
(C) m(HEEDAI) : m(MPII) = 1 : 4	2.5
(D) m(HEEDAI) : m(MPII) = 1 : 1	1.8

The other component of solutions A~D was 0.15 mol·L⁻¹ I₂.
