石灰石中氧化钙含量检测方法研究综述

Review of Research onto Methods for Determination of Calcium Oxide Content in Limestone

摘要: 随着科学技术的发展和纳米技术领域的拓宽，石灰石的应用范围正在逐步扩大，在国民经济建设中具有重要地位。但出于适应环境、生态平衡等方面的要求，尤其是随着我国小城镇建设计划的不断完善与实施，可用于生产水泥石灰岩的开采量也会逐渐大大减少。在进行石灰岩矿产资源开发过程中，为进一步提高开采效率与矿石质量，需要及时确定石灰岩质量。本文从石灰石中氧化钙含量检测方法入手，重点综述了络合滴定法、电位滴定法、火焰原子吸收光谱法和X射线荧光光谱法等氧化钙含量检测方法，并在分析现代检测方法的特点基础上，对石灰石中氧化钙含量检测方法的发展方向提出了展望，希望能够进一步提升和完善。

Abstract: With the development of science and technology and the broadening of nanotechnology, the ap-plication range of limestone is gradually expanding, which plays an important role in the national economic construction. However, due to the requirements of adapting to the environment and eco-logical balance, especially with the continuous improvement and implementation of the construc-tion plan of small towns in China, the amount of exploitation that can be used to produce cement limestone will gradually decrease. In the process of developing limestone mineral resources, in order to further improve the mining efficiency and ore quality, it is necessary to determine the quality of limestone in time. This paper starts with the detection methods of calcium oxide content in limestone, and focuses on the detection methods of calcium oxide content such as complexometric titration, potentiometric titration, flame atomic absorption spectrometry and X-ray fluorescence spectrometry. Based on the analysis of the characteristics of modern detection methods, the development direction of calcium oxide content detection methods in limestone is prospected, hoping to further improve and perfect.
