Loess has unique compositions and structural characteristics and can be used for environmental protection. Differences between the surface characteristics of the Malan loess from the suburbs of Taiyuan, Shanxi Province before and after reaction with Cr(Ⅲ) solution were studied by SEM/EDS, IR and XRD. The results showed that the Malan loess has a strong ability to remove Cr(Ⅲ) from the solution. The surface characteristics of loess include an effect on Cr(Ⅲ) in solution, as supported by the strong test evidence including the disappearance of Cr peak in the EDS spectrum, the disappearance of carbonate characteristic peaks in the infrared spectrogram, and the positive correlation between Fe and Cr peaks.
