Laboratory simulation of the dissolution of carbonate rocks sampled from Maocun,Guilin by sulfuric acid and nitric acid

  • The dissolution of carbonate rocks by sulfuric acid and nitric acid would reduce the amount of karst carbon sink, however, the quantitative relationship between these acids and carbon sink needs further study. Based on the concentrations of SO42-and NO3- in field water,this paper designed carbonic acid(0.033 mol?L-1 )+ sulfuric acid + nitric acid(0.1-1.7 mmol?L-1)(CSN acid)and sulfuric acid + nitric acid(0.1-1.7 mmol?L-1)(SN acid)dissolution experiment on carbonate rocks,and the experiment lasted 144 hours. The results show that the dissolution rates of micrite and dolomite in the CSN acid are both higher than that in the SN acid.In the CSN acid,the dissolution rate of micrite is generally higher than that of dolomite, with average values of 1.34 mg·(cm2?d)-1 and 1.21 mg·(cm2?d)-1, respectively. In the SN acid,the dissolution rates of micrite and dolomite have little difference,and their average values are 0.92 mg·(cm2?d)-1 and 0.93 mg·(cm2?d)-1, respectively. The HCO3- concentration corresponds to the result of the dissolution rate. The average HCO3- values generated by dissolution of micrite and dolomite in the CSN acid solution are 1.43 mmol?L-1 and 1.33 mmol?L-1, while the average values of HCO3- generated by dissolution of micrite and dolomite in the SN acid are 0.33 mmol?L-1 and 0.39 mmol?L-1. The concentration of HCO3- in the CSN acid decreases with the increase of acid concentration,while the concentration in the SN acid increases with the increase of acid concentration. When the concentration of SO42- and NO3- is 0.1-0.3 mmol?L-1, the dissolution rate of carbonic acid to dolomite accounts for 75.89 %-58.64%, and the dissolution rate of carbonic acid to micrite accounts for 80.21%-59.06%.When the concentrations of SO42- and NO3- are more than 0.44 mmol?L-1,the dissolution rate of carbonate rock by carbonate acid will be less than 50%.When the concentrations of SO42- and NO3- are 0.0-0.2 mmol?L-1, the field measured data is basically consistent with the simulated data. However,when the concentration of SO42- and NO3- is higher than 0.2 mmol?L-1,the field measured data is higher than the simulated data. These results indicate that nitric acid and sulfuric acid significantly affect the dissolution of carbonate rock,which could provide references for the effects of other acids on karst carbon sink.
