天然膨润土负载纳米铁的制备及其对阿莫西林的降解性能
摘要
Bentonite supported nanoscale zero-valent iorn (B-nZVI) was prepared by chemical reduction in aqueous solution and used to degrade amoxicillin. In addtion, SEM, XRD, FT-IR, BET and were used to characterize the changes in B-nZVI before and after reacting with amoxicillin. The results showed that most of the nano-iron in the products is between 30 and 90 nm dispersion well on the bentonite, reduction in aggregation and consequently improvement in the reactivity of B-nZVI. The degradation of amoxicillin was found to be fitted well-first-order kenitic model. On the basis of these results, the degradation mechanism of AMX could be attribute that β-lactam ring was opened by B-nZVI and finally this ring was broken.
