| Summary: | 碩士 === 國立臺灣海洋大學 === 生命科學暨生物科技學系 === 106 === A series of organic−inorganic hybrid zinc phosphites with extra-large channels were synthesized and characterized by single-crystal X-ray diffraction. We used the synthesized NTOU-1 material to remove mercury ions in water, and used ICP-OES to detect the change of metal ion concentration. NTOU-1 and mercury ions at a molar ratio of 10:1, after stirring for 120 minutes, its ability to remove mercury ions in water is as high as 97.4%. At the same time, zebrafish embryos are used for ecological detection. After the treatment of the aqueous solution containing mercury ions by NTOU-1, the zebrafish embryo survival rate in an aqueous environment can be improved, description NTOU-1 has a small toxic effect on the ecological environment and can remove mercury ions from water.
We also use NTOU-1 to adsorb lanthanide ions and use portable UV light. Interestingly, the powder of NTOU-1 adsorbing lanthanide metal ions can emit different color light, and can emit red light, green light, yellow light, etc. by adding different lanthanide metal ion mole ratio.
We explored the process of selective adsorption of NTOU-1. The white solid powder of NTOU-1 turned into a blue powder after adsorption of the cationic Methyl blue dye, but this phenomenon was not found in the anionic Chrome yellow dye. In addition, our liquid after adsorption of Methyl blue dye is sent to measure the UV-visible spectrum. We found that the concentration of Methyl blue dye decreased with increasing stirring reaction time and finally reached equilibrium in the presence of NTOU-1.
