The Research and Development of Ion Diffusion in Soils

土壤中离子扩散研究进展

Ion diffusion kinetics in soils can be classified into three types:negative first-order, zero-order and first-order kinetics.

本文首先从理论上分析了土壤中离子扩散的动力学问题，提出了土壤中离子扩散的三种动力学类型，即扩散的一级动力学、零级动力学和负一级动力学，并且还指出，一级动力学是土壤中离于扩散的普遍形式，负一级动力学只出现在过程的初期阶段，而扩散的零级动力学则存在于有快速表面反应的情况下。
