摘要

利用Monte Carlo方法，分别模拟二氧化硅和钼掺杂二氧化硅对Cu(Ⅱ)的吸附行为。结果表明，Cu(Ⅱ)被吸附于该纳米材料的表面和原子间隙之中；模拟发现加入少量氧化钼于二氧化硅中不会显著改变对Cu(Ⅱ)的吸附能力。同时采用广义梯度近似(GGA)的密度泛函理论(DFT)对其过程进行验证，并通过微量热技术佐证了二氧化硅及钼掺杂二氧化硅对水中Cu(Ⅱ)的吸附行为，实验发现，吸附过程的Δ

0，Δ

Abstract

The adsorption behavior of Cu(Ⅱ) on silica and molybdenum doped silica was simulated by Monte Carlo method. The results show that Cu(Ⅱ) is adsorbed on the surface of the nanomaterial and the interatomic space. It is found that adding a small amount of molybdenum oxide to silica does not significantly change the adsorption capacity of Cu(Ⅱ). At the same time

the generalized gradient approximation (GGA) density functional theory (DFT) was used to verify the process

and the adsorption behavior of Cu(Ⅱ) in water by silica and molybdenum doped silica was verified by microcalorimetry. It was found that the adsorption process had Δ

van der Waals force as the adsorption driving force

and the molecular simulation was consistent with the experimental results.
