| Abstract: | The acid and alkaline buffering capacity of pit mud samples were studied. By using a curve fitting method based on acid-base titration,the acidic and alkaline buffering capacity of the 4 pit mud samples were511.38 mmol/kg and 205.50 mmol/kg,961.87 mmol/kg and 279.99 mmol/kg,341.17 mmol/kg and 69.21 mmol/kg,336.28 mmol/kg and 116.58 mmol/kg respectively. The results showed that the acidic and alkaline buffering capacity of different pit mud samples were quite different,the acidic buffering capacity of the same pit mud sample is higher than that of alkaline buffering capacity,and the acidic and alkaline buffering capacity of pit mud samples with shorter year were higher than that of pit mud samples with longer year. |
