摘　　要：在固定pH值的条件下,采用盐酸滴定石灰石浆液的方法,重点研究和分析了温度、无机添加剂(Na2SO4)和有机添加剂(己二酸)对石灰石溶解特性的影响.结果表明:较低的pH值和较高的温度有利于石灰石的溶解;Na2SO4和己二酸均能促进石灰石的溶解率,并且pH值越增大,促进效果越好.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 （Na2SO4） and organic additives （adipic acid） effect on the limestone dissolution. The above results show that lower pH value and higher reaction temperature are favorable to limestone dissolution; Na2SO4 and adipic acid can promote limestone dissolution rate, and the better promotion effect is found on the limestone dissolution rate with the increasing of oH value.
