表面分析技术新进展及在矿物工程研究中的应用--原子力显微镜

Development of Surface Analytical Techniques and their Application in Mineral Engineering——Atomic Force Microscopy

简要阐述了原子力显微镜(Atomic Force Microscopy)操作原理;结合我们课题组的研究工作,从矿物表面疏水性和表面电性的表征、矿物颗粒与气泡和药剂间作用力分析以及矿物表面微观形貌成像等方面对原子力显微镜在矿物工程研究领域的应用情况作了概括介绍。原子力显微镜技术能与各种检测表征技术结合,在不同领域得到持续广泛的应用。

Atomic force microscopy(AFM)is a well established tool for surface imaging and surface interaction force measurement.In this review,the basic principles of AFM is briefed.The application of atomic force microscopy in the field of mineral engineering research was reviewed and discussed with respect to the application of AFM in our research group,such as characterization of the mineral surface hydrophobicity,surface charge features,bubble-particle interaction,surfactant adsorption at the mineral surface,and mineral morphology analysis.The AFM technology is continuously developing,new AFM systems combining with other analytical techniques have been using in the many research areas,such as Electrochemical AFM(EC-AFM)and atomic force microscope infrared spectroscopy(AFM-IR).
