Experimental Study on Promoting the Dissolution Factors of Limestone

At a fixed pH value,the activity of limestone is studied by using hydrochloric titration limestone slurry method,the main attention is focused on the research and analysis of reaction temperature,inorganic additives(Na 2 SO 4) and organic additives(adipic acid) effect on the limestone dissolution.The above results show that low er pH value and higher reaction temperature are favorable to limestone dissolution;Na 2 SO 4 and adipic acid can promote limestone dissolution rate,and the better promotion effect is found on the limestone dissolution rate w ith the increasing of pH value.
