【摘要】：本文以微晶纖維素(MCC)為載體,采用原位生成法,以高錳酸鉀(KMnO_4)和硫酸錳(MnSO_4)為納米二氧化錳前驅體,制得單層覆蓋均勻的微晶纖維素基復合分層材料MCC-MnO_2,并對其微觀結構和化學構成進行了表征,通過模擬Pb~(2+)吸附實驗探討了時間t和前驅體高錳酸鉀(KMnO_4)的濃度對吸附效果的影響。實驗結果表明:當高錳酸鉀的濃度為4 mmol/L、吸附時間為400 min時,MCC-MnO_2對Pb~(2+)的吸附容量達到最大值,其飽和吸附容量高達265.3 mg/g。
[Abstract]:In this paper, using microcrystalline cellulose (MCC) as carrier, in situ generation method, using potassium permanganate (KMnO4) and manganese sulfate (MnSO4) as nanocrystalline manganese dioxide precursors, MCC-MnO _ 2 composite laminated material with homogeneous monolayer covering microcrystalline cellulose was prepared. The microstructure and chemical composition of MCC-MnO _ 2 were characterized. The effects of time t and concentration of precursor KMnO4) on the adsorption of Pb~(2 were investigated by simulated Pb~(2) adsorption experiments. The results showed that when the concentration of potassium permanganate was 4 mmol / L and the adsorption time was 400 min, MCC-MnO _ 2 could adsorb Pb~(2). Maximum capacity, Its saturated adsorption capacity is 265.3 mg / g.
