| description | In this study, diffusion coefficients of ammonium vanadate at tracer concentrations in artificial saliva with and without sodium fluoride, at different pH values, were measured using an experimental model based on the Taylor dispersion technique. Ternary mutual diffusion coefficients (<i>D</i><sub>11</sub>, <i>D</i><sub>22</sub>, <i>D</i><sub>12</sub>, and <i>D</i><sub>21</sub>) for four aqueous systems {NH<sub>4</sub>VO<sub>3</sub> (component 1) + β-cyclodextrin (β-CD) (component 2),} {NH<sub>4</sub>VO<sub>3</sub> (component 1) + β-cyclodextrin (HP-β-CD) (component 2)}, {NH<sub>4</sub>VO<sub>3</sub> (component 1) + sodium dodecyl sulphate (SDS) (component 2)} and {NH<sub>4</sub>VO<sub>3</sub> (component 1) + sodium hyaluronate (NaHy) (component 2)} at 25.00 °C were also measured by using the same technique. These data showed that diffusion of ammonium vanadate was strongly affected in all aqueous media studied. Furthermore, a significant coupled diffusion of this salt and β-CD was observed through the non-zero values of the cross-diffusion coefficients, <i>D</i><sub>12</sub>, allowing us to conclude that there is a strong interaction between these two components. This finding is very promising considering the removal, from the oral cavity, of vanadium resulting from tribocorrosion of Ti-6Al-4V prosthetic devices. |
