石英是土壤和沉积物中的重要矿物组成部分,前人已在不同程度上对其表面基团和表面物理化学性质进行了研究。事实上,石英(SiO2)具有多种同质多象变体。即同是化学成分为SiO2的矿物,其晶体结构可能是大不相同的,也就形 Quartz is an important mineral component in soils and sediments. Previously, its surface groups and surface physicochemical properties have been studied in various degrees. In fact, quartz (SiO2) has a variety of homogeneous multi-variant. That is the same chemical composition of SiO2 minerals, the crystal structure may be very different, it is shaped
