采用一种新方法合成了由六氰合铁钛钾(PTH)与二氧化硅组成的多孔球形杂化材料。其过程分为两步:首先将无定型二氧化钛接枝于球形二氧化硅载体的孔壁上;然后利用TiO2+和K4[Fe(CN)6]的反应将孔道内的二氧化钛转化为PTH。所制备的杂化材料通过低温氮吸附、XRD、FTIR和XPS等方法进行了表征。结果表明PTH涂层被成功负载于二氧化硅小球的内部孔壁上。所得杂化材料在高酸度和高盐度的情况下仍然对Cs+离子表现出了很强的去除能力和很高的分配系数。 A new method was used to synthesize a porous spherical hybrid material composed of iron hexacyanoferrate potassium titanate (PTH) and silica. The process is divided into two steps: firstly, the amorphous titania is grafted to the pore wall of the spherical silica carrier; and then titanium dioxide in the pore is converted into PTH by the reaction of TiO2 + and K4 [Fe (CN) 6]. The hybrid materials prepared by low temperature nitrogen adsorption, XRD, FTIR and XPS and other methods were characterized. The results show that the PTH coating was successfully supported on the inner wall of silica beads. The resulting hybrid materials still show a strong removal ability and a high partition coefficient for Cs + ions at high acidity and high salinity.
