| Zusammenfassung: | In this study, D-Xylose coated MNPs were synthesized and used as draw agent in forward osmosis (FO) process for water purification. Response surface methodology (RSM) was utilized for the design and optimization of synthesis parameters. In order to characterize the synthesized MNPs, FTIR, TEM, VSM, and UV characterization techniques were performed. The effect of independent parameters including D-Xylose mass, MNPs mass, and synthesis time on the osmotic pressure was investigated. Based on the optimization results, the osmotic pressure of a 2 wt./v% draw solution using 2.66 g D-Xylose, 0.13 g MNPs, and a 7.11 h synthesis time was 0.81 bar as the highest value. Using D-Xylose coated MNPs as draw agent and deionized water as the feed, the initial FO water flux was 2.98 LMH. Reusing the recovered MNP draw agent in two more consecutive tests resulted in the reduction of water flux to 2.68 and 2.30 LMH, respectively. Moreover, using 0.01 M NaCl solution as the feed, the initial water flux was reported as 1.3 LMH. To remove the draw agents from suspension, external magnetic field was applied to obtain a water turbidity of 0.08 NTU |
