Abstract
Iron-based metal-organic framework (MIL-100(Fe)) was successfully synthesized by sonochemical method at the frequency of 20.5kHz, power of 1080 W in 10 minutes. Several physical measurements were conducted to characterize the MIL-100(Fe) including XRD, FT-IR, Raman, BET, and SEM methods. The analysis results show that the material has characteristic diffraction peaks at 11o, 19o, 24o, and 28o, the specific surface area of the material reaches 1080 m2/g according to BET, and the particle size from 200-400 nm according to SEM. The chloroquine phosphate loading capacity of MIL-100(Fe) was evaluated according to different adsorption kinetic and isothermal models. The results show that the chloroquine phosphate loading process by material consists of two stages: surface adsorption and intra-particle diffusion. The maximum chloroquine phosphate adsorption capacity of the material reached 236 (mg/g) according to the Langmuir model.
