摘要
The dissolution rate of dolomite and limestone by acid rain in Guilin is studied. The results showed that the conductivity and pH of dolomite and limestone in acid rain soak solution as a function of time were linear. In the same condition, the dissolution rate of limestone is larger than dolomite,both dissolution rates are in the same order of magnitude. In the open or the closed system, the change trend of the conductivity and pH of dolomite and limestone are similar. In the same pH, the dissolution rate of limestone in the great rainfall is 3-4 times larger than that in the little rainfall. Therefore, the acidity of rain and the rainfall are important factors which influence the dissolution rate.
