摘要
在微波辅助球磨作用下用均三苯甲酸和Zn(CH_3COO)_2·2H_2O制备Zn-MOFs,结构通过IR、XRD、SEM、TG等对结构确认。将制备的Zn-MOFs用于对刚果红的除去,并在Xe光和自然光的条件下进行移除对比。结果显示,当刚果红的浓度分别为100、50、30和10 mg/L,在Xe光和自然光照射3h的移除率分别为56.1%, 83.9%, 97.2%和26.8%,34.9%, 62.2%。
Zn-MOFs were prepared from tribenzoic acid and Zn(CH_3COO)_2·2H_2O by microwave assisted ball milling.The structure of MOFs was confirmed by IR, XRD, SEM and TG. Prepared Zn-MOFs were used to remove Congo red, and the removal rates under the conditions of Xe light and natural light were compared. The results showed that when Congo red concentration was 100, 50, 30 and 10 mg/L, the removal rates after 3-hour treatment were 56.1%,83.9%,97.2% by Xe light and26.8%, 34.9% 62.2% by natural light, respectively.
