摘要:
为制备兼具识别和去除重金属离子的功能材料,首先采用常规St?ber法制备二氧化硅(SiO2)微球,通过调节正硅酸乙酯(TEOS)与氨水的比例,得到四种不同粒径的起始微球,然后用NaOH溶液刻蚀以获得多孔SiO2微球。进而将-CH2CH2CH2NH2基团(氨丙基)引入到多孔微球,通过席夫碱生成反应,将以氟硼二吡咯(BODIPY)为荧光体的荧光小分子探针接枝到多孔微球上,最终获得4种尺寸且具有优良荧光和传感性能的多孔荧光微球SiO2-NH2-BODIPY-Aldehyde[SiNBPA600; SiNBPA100;SiNBPA60;SiNBPA10(数字表示微球粒径,单位为nm)]。SiNBPA对Hg+具有单一选择性识别能力,在自然光照射下,Hg+会导致明显的颜色变化。当SiNBPA多孔微球结合Hg+离子时,SiNBPA600,SiNBPA100,SiNBPA60,SiNBPA10的荧光强度分别猝灭到原来的1/14,1/15,1/25,1/16,每克SiNBPA微球对Hg+的吸附效率分别达1.29,1.43,1.54 g和1.36 g。实验结果表明:同等条件下比较,SiNBP60在检测识别和吸附去除Hg+性能方面最优良。
Abstract:
To prepare functional materials that can identify and remove heavy metal ions, SiO2 microspheres were first prepared by the conventional Stober method. By adjusting the ratio of ethyl orthosilicate(TEOS) to ammonia, four initial SiO2 microspheres with different particle sizes were obtained. The initial SiO2 microspheres were etched with NaOH solution to obtain porous SiO2 microspheres. -CH2CH2CH2NH2 groups were then introduced into the porous microspheres. Via Schiff base formation reaction, small fluorescent molecules are grafted onto porous microspheres. Finally, SiO2-NH2-BODIPY-Aldehyde[SiNBPA600, SiNBPA100, SiNBPA60, SiNBPA10(the number represents the nanospheres’ particle size, and the Unit is nm) were obtained with excellent fluorescence and sensing properties. SiNBPA has selective recognition ability to Hg+ ions, and under natural light, the addition of Hg+ will cause significant color changes. When SiNBPA binds to Hg+, the fluorescence intensities of SiNBP600,SiNBP100,SiNBP60, and SiNBP10 are quenched to 1/14,1/15,1/25 and 1/16 that of original ones, respectively, and the adsorption efficiency of Hg+ per gram of fluorescent microspheres with different particle sizes reached 1.29, 1.43, 1.54 g and 1.36 g, respectively. The experimental results show that SiNBP60 is better than other fluorescent microspheres in detection, recognition and adsorption removal of Hg+.
