ADSORPTION OF RADIOFLUORINE 18F IONS ONTO METAL ORGANIC FRAMEWORK

Fluoride is one of the drinking water contaminants regulated by the World Health Organization. The reduction of fluoride concentration to a safe range is of paramount importance to human life. Moreover, the fast and high-capacity removal of radioactive 18Fwastes is still challenging. Metal organic frameworks (MOFs) are a hybrid class of materials that can diminish such contaminants via both adsorption and catalysis processes. In this work, we synthesize three different MOFs and study their adsorption behavior towards fluoride ion removal. The synthesized materials were characterized using X-ray diffraction, FT-IR and scanning electron microscopy. Following investigation we showed that the as-synthetized materials were highly stable and had significantly effective fluoride adsorption performance What is more, the activity of fluoride captured by the material Al-Fu MOF is 603 mu Ci in 40 mg of this material, i.e., the removal efficiency is about 98%.
