目前应用Langmuir吸附等温式来探讨土壤对磷酸离子的吸附作用,较为广泛。自从Olsen(1957)系统地报道以来,从机理到结合生产实际的研究已有大量的报道,我国近年来也有研究。由于土壤本身组成的复杂性,多数学者用纯物质(如纯粘土或铁与铝的含水氧化物等)进行吸附等温式的机理研究,已取得了很多结果。在Larson Langmuir adsorption isothermal equation currently used to explore the adsorption of phosphate ions on the soil, more extensive. Since the systematic report by Olsen (1957), there have been a lot of reports on the mechanism from the mechanism to the actual production. Our country has also studied in recent years. Due to the complexity of the composition of the soil itself, many scholars have made a lot of studies on the isothermal mechanism of adsorption using pure substances such as pure clay or hydrous oxides of iron and aluminum.
