【摘要】：水環(huán)境的污染問題在全球都備受關注,其中以放射性元素銫離子代表的具有放射性的可溶性堿金屬離子和以芳香族污染物代表的有機污染物尤其值得關注。雖然多種多孔材料已經被發(fā)現并應用在吸附處理污染物上,但是因為普魯士藍類配合物不僅對銫離子有選擇性吸附,而且對芳香族污染物也有較強的吸附性,所以普魯士藍類配合物作為吸附劑具有較大潛力。普魯士藍類配合物的吸附能力與介觀結構和吸附位點相關,傳統方法合成的中空普魯士藍類配合物結晶度較低限制了吸附位點數量的增加。為了得到具有較多吸附位點的中空普魯士藍類配合物,本文首先通過配位復制的方法制備出具有規(guī)則形貌的金屬氧化物@普魯士藍類配合物的核殼結構。接著通過溫和的刻蝕方法去除核層金屬氧化物,從而制備出中空結構的普魯士藍類配合物顆粒。本文選擇氧化亞銅作為前驅體,成功合成出中空結構銅鐵普魯士藍和中空結構銅鈷普魯士藍,并選擇中空銅鐵普魯士藍測定銫離子吸附性能,選擇中空銅鈷普魯士藍測定亞甲基藍吸附性能。
[Abstract]:The problem of pollution of water environment has attracted much attention all over the world. Radioactive soluble alkali metal ions represented by cesium ions and organic pollutants represented by aromatic pollutants are of particular concern. Although many porous materials have been found and used in adsorption. Handling contaminants. However, Prussian blue complexes not only selectively adsorb cesium ions, but also have strong adsorption on aromatic pollutants. Therefore, Prussian blue complexes have great potential as adsorbents. The adsorption capacity of Prussian blue complexes is related to mesoscopic structure and adsorption sites. The low crystallinity of hollow Prussian blue complexes synthesized by traditional methods limited the increase of adsorption sites. In order to obtain hollow Prussian blue complexes with more adsorption sites. In this paper, the core-shell structure of regular metal oxide @ Prussian blue complexes was prepared by coordination replication, and then the nuclear layer metal oxides were removed by mild etching. Thus the hollow structure of Prussian blue complex particles were prepared. In this paper the hollow structure copper iron Prussian blue and the hollow structure copper cobalt Prussian blue were successfully synthesized by using cuprous oxide as the precursor. The adsorption property of cesium ion was determined by hollow copper iron Prussian blue and methylene blue was determined by hollow copper cobalt Prussian blue.
