| Research Abstract |
It is thought that the effect of negative pressure on the dissolution of CO_2 gas in NaOH solution exist. There is a high possibility that the increase of dissolution rate of CO_2 gas and the decrease of saturated dissolved CO_2 concentration occur. However, changes due to the effect of negative pressure are little. Therefore, advanced studies under the lower CO_2 gas concentration and the lower negative pressure are needed.
