摘要

通过热分析、X 射线光电子能谱、扫描电子显微镜和氮孔测定法，对无烟煤基 Purolate 标准吸附剂吸附铁、锰、硫酸盐和亚硝酸盐离子前后的情况进行了研究。热分解指数、不同温度范围内的质量损失与 X 射线光电子能谱（样品表层的相对原子浓度）、扫描电子显微镜（显微照片分析）和氮孔测定法（样品的比表面值）的结果之间建立了相关性。

Surface State of Purolate Standard Activated Carbon after Sorption of Minerals

Anthracite-based Purolate standard sorbent is studied before and after sorption of iron, manganese, sulfate, and nitrite ions, by thermal analysis, X-ray photoelectron spectroscopy, scanning electron microscopy, and nitrogen porosimetry. Correlations are established between the thermal decomposition indices, the mass loss in different temperature ranges, and the results of X-ray photoelectron spectroscopy (relative atomic concentrations in the surface layer of samples), scanning electron microscopy (analysis of microphotographs), and nitrogen porosimetry (specific surface values of the samples).
