Figure 4

Thymol release profiles under regular aqueous media conditions (25 °C, pH 7, NaCl 0.5%) showing release rates according to different interactions (a). Release rate coefficients, k, obtained after linearization of the experimental release profiles using a modified Elovich equation in order to investigate effects of temperature (b), pH (c) and salinity (d) on the thymol release.
