概要 |
Any strategy of CO_2 sequestration needs to clear the CO_2 solubility into water and the dissolution behavior. We measured the pH distribution around a dissolving CO_2 droplet in a high pressure vessel by using a 2 color LIF method. Qunine and sulforhodamine were used as fluorescence dyes. Molar absorption coefficient and emission intensity of quinine depends on pH of aqueous solution, while those of sulforhodamine are not affected by pH. The ratio of these fluorescence intensities represents pH at each point of image. The map of pH around the dissolving droplet gives also a map of CO_2 concentration, from which the solubility can be estimated. |
