水溶性胶体盐碱土水解聚马来酸酐(HPMA)原子力显微镜(AFM)Water-Dispersible Colloids Saline-Alkali Soils Hydrolyzedpolymaleic Anhydride (HPMA) Atomic Force Microscopy (AFM)



Recent studies indicated that water-dispersible colloids play important roles in transportation of nutrients and contaminants in soils. However, there are few systematic studies on the water-dis- persible colloids in soil so far. In this study, the water-dispersible colloids in the saline-alkali soils in Zhaodong, northeast of China, were extracted and further characterized by Atomic force microscopy (AFM), X-ray Diffraction (XRD), X-ray photoelectron spectroscopy (XPS). AFM observation indicated that the water-dispersible colloids contain some large plates and many small spherical particles with a wide range of size distribution. XRD and XPS measurement revealed that the wa-ter-dispersible colloids are composed of kaolinite, illite, calcite, quartz and humic acid. The wa-ter-dispersible colloids extracted from the saline-alkali soils pretreated with hydrolyzed polymaleic anhydride (HPMA) and an agricultural soil were also investigated and compared. The differences of the water-dispersible colloids in the saline-alkali soils and agricultural soil implied that the saline-alkali condition facilitate the formation of the large colloids. The present study is very useful for enriching the knowledge of the saline-alkali soils and understanding the reclamation mechanism of HPMA for the saline-alkali soils.
