砂质壤土中重金属离子运移阻滞系数的模拟
Simulation on retardation factor of heavy-metal transport in sandy loamy soil
摘要
Abstract
The objective of this study was to characterize the retardation factor of copper in sandy loam. In this paper, adsorption isotherm was determined by using the batch and flow equilibrium procedure. With the different values of linear distribution coefficient, the retardation factor of copper in the soils was obtained. At the same time, the optimized values of the retardation factor were estimated by using the effluent data from the flow equilibrium experiments with the software CXTFIT2.1. It was shown that the flow equilibration method gave same precision as the conventional batch equilibration method.关键词
