将吸附饱和的Pb(II)和Zn(II)的nZVI-Fe3O4置于100 mL具塞锥形瓶中,加入50 mL一定初始浓度的HCl溶液,放入水浴恒温振荡器中(120 r/min),在不同时间、温度下进行脱附,脱附结束后,将锥形瓶从水浴恒温振荡器中取出并用离心...
In addition, Ti3C2Tx/nanofibrillated cellulose (NFC) was obtained by LiF/HCl etching and alkylation of Ti3C2Tx complexed with NFC31. Due to the presence of NFCs, which suppressed aggregation problems and increased electrolyte contact, the assembled ZHSCs exhibited large specific capacities (92.1 ...
