About 90 points of diffusion coefficient of lithium bromide (LiBr) in aqueous solution were measured by holographic interferometry in the temperature range of 20∼50°C and the concentration range of 0.4∼55mass%.<br> A correlation among concentration, temperature and diffusion coefficients was done, and an empirical equation to calculate the diffusion coefficient in the concentration and the temperature ranges mentioned above was proposed. Differences between experimental values and correlated expression were almost within±2%.<br> Accuracy of the measured diffusion coefficients was discussed and the measurements are shown to be made within error of ±6.8%.
