The morphology of sediment particles plays an important role in interfacial interactions.The difficulties in complex morphological description significantly limit the research on interfacial interactions.In this study,images of a single sediment particle extracted from electron microscope photos were used to analyze the gray values and present the probability of shape of the sediment particles.Moreover,the morphological features of the sediment particles were qualitatively described using the fractal method(surface area-volume method).The fractal dimension D of a single sediment particle was calculated to analyze the features and quantitative complexity of the sediment particle morphology.Results indicate that the probability of shape can provide intuitive morphological structure and fully describe the complex morphological characteristics of sediment particle surfaces.The fractal dimension abstractly described the complexity of the morphology of a sediment particle surface and matched well with the experimental results.The methods discussed in this study are suitable for describing the complex morphology of the sediment particle surface and lay the scientific foundation for further research on the interfacial interaction between the sediment particle and the pollutant.
